Choose the Right Cardiologist, Test and Inland Empire Office Before Your Visit

Cardiology Specialists Medical Group has served patients in California’s Inland Empire since 1992. The practice combines general cardiology with advanced imaging, electrophysiology, interventional cardiology, vascular treatment, structural-heart procedures and women’s cardiovascular care.

This guide brings the important patient information into one page: which specialist fits the problem, what heart tests mean, how advanced procedures differ, where the current offices are, which sites are telehealth-only, how to prepare for a first visit, what insurance details matter, and when a heart symptom should bypass the clinic completely and go straight to emergency care.

Plan an appointment Find the right office Understand heart testing
Chest pain or possible heart attack? A cardiology office appointment is not emergency care. Call 911 for new or severe chest pressure, squeezing or pain, significant shortness of breath, loss of consciousness, or concerning symptoms such as chest discomfort spreading to the arm, back, neck or jaw with sweating, nausea or lightheadedness.
Name check: the official practice is Cardiology Specialists Medical Group—plural “Specialists.” Searches for “Cardiology Specialist Medical Group” commonly lead to this Inland Empire practice.

Which type of Cardiology Specialists Medical Group care fits your problem?

GENERAL CARDIOLOGY Diagnosis, prevention and ongoing heart care

Start here for high blood pressure with cardiac concerns, coronary disease, heart failure, valve disease, abnormal ECG findings, shortness of breath, palpitations, cardiovascular risk evaluation or follow-up after hospitalization.

Best first route when you need a heart diagnosis or long-term medical treatment rather than a specific procedure.
ELECTROPHYSIOLOGY Heart rhythm problem

Electrophysiology focuses on the heart’s electrical system. It becomes relevant for selected arrhythmias, rhythm-monitor abnormalities, ablation discussions and pacemaker-related care.

CSMG’s current physician roster includes an electrophysiologist and the service list includes EP studies, ablation and pacemaker insertion.
INTERVENTIONAL / STRUCTURAL Blocked artery, valve or vascular procedure

Interventional cardiologists use catheter-based techniques for coronary, peripheral and structural-heart disease when the patient’s condition and testing support a procedure.

CSMG lists catheterization, angioplasty, TAVR, MitraClip, Watchman, vascular interventions and other advanced procedures.
Practical routing rule: schedule general cardiology when you need a diagnosis or medical plan; ask specifically for rhythm expertise when the problem is electrical; and use an interventional or structural-heart specialist when a cardiologist has identified a condition that may need a catheter-based procedure.

Current physician roster

How to choose the right CSMG cardiologist

The current physician page lists cardiologists with overlapping skills but different areas of concentration. You usually do not need to decide alone; the scheduler can route the referral based on the diagnosis and requested service.

CSMG physicians and the expertise highlighted by the practice
Physician Highlighted expertise Patient situation where that expertise may matter
Kaustubh V. Patankar, MD, FACC Medical director; general and interventional cardiology; pacemakers; complex coronary and peripheral interventions. Complex coronary or vascular disease and selected device/interventional care.
Nader Nashaat Attia, DO Cardiology, cardiac catheterization, TEE and nuclear cardiology. General cardiac evaluation with potential invasive or advanced imaging needs.
Jeremy Cox, DO Cardiac imaging, echocardiography, nuclear cardiology, vascular ultrasound and heart-failure/valve care. Imaging-heavy evaluation, valve disease, coronary disease and congestive heart failure.
Bradley S. Messenger, MD Electrophysiology. Arrhythmias, electrical-system problems and selected rhythm procedures.
Christopher Seaman, MD General and interventional cardiology, echocardiography and nuclear cardiology. Coronary disease evaluation and minimally invasive catheter-based treatment.
Mimi Sen Biswas, MD, MHSc Women’s heart care, cardiovascular imaging, prevention and cardiac CT. Women’s cardiovascular risk, prevention and imaging-focused evaluation.
Niraj V. Parekh, MD Interventional cardiology, structural heart disease, vascular disease and peripheral interventions. Coronary, peripheral, carotid, aneurysm or structural-heart treatment.
Jatin N. Amin, MD, FACC Cardiology, echocardiography and nuclear cardiology. General cardiovascular evaluation and non-invasive imaging.
Sandeep Sangodkar, DO, FACC Non-invasive cardiac imaging, preventive care and cardiovascular wellness. Prevention, risk reduction and imaging-focused cardiology.
Don Tait, DO Interventional cardiology with coronary, peripheral and structural interventions. Selected coronary, vascular and structural-heart procedures.
Website-count caution: the current physician roster names 10 physicians, while a homepage banner still displays “9 Cardiologists.” Use the live physician directory and appointment office—not a marketing counter—to confirm current provider availability.
What the practice treats

Heart and vascular conditions managed by Cardiology Specialists Medical Group

↻
Arrhythmias

Abnormal heart rhythms that may cause palpitations, dizziness, fainting or other symptoms.

♥
Coronary artery disease

Narrowing or blockage of arteries that supply blood to the heart muscle.

HF
Heart failure

A condition in which the heart does not pump or fill efficiently enough to meet the body’s needs.

V
Heart valve disease

Valve narrowing or leakage that can change blood flow through the heart.

A
Aortic disease

Conditions involving the body’s major artery, including selected aneurysm-related problems.

P
Peripheral vascular disease

Reduced or abnormal blood flow involving arteries or veins outside the heart.

DVT
DVT and pulmonary embolism

Blood-clot conditions affecting veins and, when a clot travels, the pulmonary circulation.

CM
Cardiomyopathy

Disease of the heart muscle that can affect pumping, filling or rhythm.

S
Stroke and vascular risk

Cardiovascular evaluation may be relevant when rhythm, carotid or structural-heart disease contributes to stroke risk.

Diagnostic testing

What the CSMG heart tests are designed to answer

Cardiac tests listed by the practice
Test What it evaluates Useful preparation question
Electrocardiogram / ECG Records the heart’s electrical activity and rhythm. “Should I take my normal medicines before the test?”
Echocardiogram Ultrasound images show heart structure, pumping function and valve movement. “Is this a standard echo or another type such as TEE?”
Exercise stress test Assesses how the heart responds to physical exertion. “Which medicines, food, caffeine or clothing instructions apply?”
Nuclear stress test Uses a tracer and imaging to evaluate blood flow to heart muscle under stress and rest conditions. “Do I need caffeine restrictions and how long should I expect to be there?”
EP study Investigates the electrical pathways responsible for selected arrhythmias. “Which rhythm medicines should I take or hold, and is sedation planned?”
MUGA scan Measures how effectively the ventricles pump blood. “Why was MUGA selected instead of an echocardiogram for my situation?”
Tilt-table study May help investigate fainting, dizziness and blood-pressure or heart-rate responses to position. “Are there fasting or medication instructions before the study?”
Do not stop heart, blood-pressure, rhythm or blood-thinning medication on your own. Test preparation varies. Ask the ordering office for the exact medication, fasting and caffeine instructions connected with your test.

Appointment workflow

How to schedule without being routed to the wrong office or specialist

Know why you were referred Have the referral diagnosis, abnormal test or main symptom available when you call.
Tell the scheduler whether this is new or established care A new consultation may need more records and authorization than a routine follow-up.
Give the exact insurance product and medical group In California, the insurer name alone may not determine specialist access. Your IPA or assigned medical group can be equally important.
Ask whether a referral or authorization is already on file Do this before choosing a date if your plan requires specialist authorization.
Ask which cardiologist fits the diagnosis Rhythm, interventional, structural, vascular, imaging and women’s-heart needs may be routed differently.
Confirm the location CSMG has multiple Inland Empire offices and two current listings are telehealth-only.
Ask whether testing is planned the same day A consultation and an echocardiogram, stress test or monitor placement may have different preparation instructions.
Save the direct office details Record the address, physician, arrival time, phone number and any instructions.
Appointment call script
“I need a cardiology appointment for [diagnosis or symptom]. I am a [new/returning] patient. My insurance is [full plan] and my medical group or IPA is [name]. Can you confirm whether my referral and authorization are on file, which cardiologist is appropriate, the exact office location, and whether any testing or special preparation is planned?”

First visit

What to bring to Cardiology Specialists Medical Group

CSMG’s patient-forms page specifically tells patients to bring identification, their insurance card and a list of current medications.

Government-issued photo ID
Current insurance card
Referral or authorization information when required
Medication names, strengths and doses
Medication allergy list
Recent ECG, echo, stress-test or monitor reports
Hospital discharge paperwork if recently admitted
Prior catheterization or stent information
Pacemaker/device card if applicable
Blood-pressure or heart-rate log when useful
Family history of early heart disease
Three questions you most need answered
Useful cardiology shortcut: do not write only “blood thinner,” “water pill” or “heart medicine.” Bring the actual medication name, strength and frequency because changes in anticoagulants, diuretics, antiarrhythmics and blood-pressure medicines can matter.

Virtual care

When telehealth can work for a cardiology visit—and when it cannot

Good telehealth uses

Selected follow-ups, medication discussions, review of home blood-pressure readings and some test-result conversations may be suitable when the cardiologist agrees.

Needs an in-person test

An ECG, echocardiogram, stress test, monitor placement or physical examination may require travel to an appropriate site.

Not for an emergency

Telehealth should not delay 911 evaluation for possible heart attack, stroke, cardiac arrest or another acute cardiovascular emergency.

Before a virtual cardiology follow-up

Record recent blood-pressure readings
Record resting heart-rate readings
Have medications beside you
Know your current weight when heart failure is being managed
Write down new symptoms and when they occur
Test your camera, microphone and internet before the visit
Insurance and IPA routing

How CSMG insurance participation actually works

The practice publishes a broad list of insurers, health plans and IPAs. The most important point is that a company name alone does not guarantee coverage for your exact cardiologist, procedure or location.

Examples from the current CSMG insurance page
Insurance / arrangement Examples currently listed What to verify
Aetna EPO, Managed Choice, PPO and HMO products are listed. Exact network, cardiologist, office and referral requirements.
Anthem Blue Cross Pathway PPO, Prudent Buyer PPO and Select PPO appear on the list along with HMO participation. Whether the assigned medical group authorizes CSMG.
Blue Shield of California PPO is specifically listed. Network and specialist benefits.
Cigna PPO, HMO and Open Access Plus. Exact product and location participation.
Medicare / Medi-Cal arrangements Several listed IPAs include Medicare, Medi-Cal or combined arrangements. Assigned IPA/medical group and referral authorization.
IEHP-related arrangements IEHP appears within several listed contracting arrangements. Current provider assignment and the exact benefit product.
Insurance verification script
“My insurance is [full product name], member ID [number], and my assigned IPA/medical group is [name]. I am scheduled with [cardiologist] at [location] for [consultation/test/procedure]. Is the physician and location contracted for my exact plan? Do I need a referral or prior authorization, and does the authorization also cover the planned test?”
Important for cardiac testing: an office consultation being covered does not automatically mean a nuclear study, CT, procedure, hospital service or implanted device is authorized. Ask about each separately.

Patient access

Cardiology Specialists Medical Group patient portal

The official CSMG website currently links patients to FollowMyHealth for patient-portal access.

1 Start at CSMG

Use the patient-portal button on the practice’s official website.

2 Open FollowMyHealth

The official CSMG link redirects to the FollowMyHealth sign-in system.

3 Use your existing account

Sign in with the credentials associated with the connected patient record.

4 Call if your record is not connected

A connection or invitation problem is different from simply forgetting a password.

Avoid the wrong portal: the final sign-in is hosted by FollowMyHealth, but the safest starting route is the patient-portal link on CSMG’s official site.
Open FollowMyHealth
Save check-in time

CSMG new-patient, records and update forms

The practice says its online forms are encrypted and HIPAA-compliant and can be completed without printing.

New Patient Intake

Use before the first visit to provide patient and clinical information needed for registration.

Medical Release Authorization

Use when authorization is needed to release or obtain medical information.

Returning Patient Update

Use when an established patient’s demographic, insurance or medical information needs updating.

Bring these even if the online form is complete: identification, insurance card and an accurate current-medication list.

Self-pay cost protection

Good Faith Estimate rights before non-emergency cardiology care

CSMG publishes the federal Good Faith Estimate notice for patients who do not have insurance or who choose not to use insurance.

Ask before the service Request an estimate for expected non-emergency health-care charges.
Identify the planned services Ask whether the estimate includes the consultation, test, procedure, physician fee and any facility-related services expected.
Keep the estimate Save the written copy or a clear picture of it.
Compare the final bill Match the provider, service and amount rather than comparing only a single total.
Know the $400 rule The CSMG notice states that a bill at least $400 above the Good Faith Estimate may be disputed through the federal patient-provider dispute process.
Cardiology-specific cost question: ask whether a test or procedure is performed in the office, hospital, imaging center or other facility. The site of service can affect the final bill.
After the test

What to do after an ECG, echo, stress test or cardiac monitor

You were told the ECG is abnormal Ask what specific finding was seen and whether it represents an emergency, a chronic finding or something needing another test.
Your echocardiogram mentions ejection fraction Ask the cardiologist to explain what the number means in the context of your symptoms, heart structure and prior studies.
Your stress test is “positive” or “abnormal” Ask whether the finding suggests reduced heart-muscle blood flow and what the recommended next step is.
Your monitor captured an arrhythmia Ask what rhythm occurred, how long it lasted, whether symptoms matched it and whether medication, observation or electrophysiology evaluation is recommended.
The portal or office has no result yet Confirm the test location and ask whether the study is awaiting interpretation rather than repeating the test automatically.
Your symptoms have become worse while waiting Do not wait for the routine follow-up when symptoms may represent an emergency. Use appropriate urgent or emergency care.
Result follow-up script
“I had [test] on [date] at [location]. Can you confirm whether the study has been interpreted? What was the main finding, does it change my diagnosis or medication, and what is the next step?”
Do not wait for an office callback

Heart symptoms that need emergency evaluation

Call 911 for possible heart attack symptoms. Warning signs can include chest pressure, squeezing, fullness or pain; shortness of breath; discomfort in an arm, the back, neck, jaw or stomach; cold sweat; nausea; unusual lightheadedness or collapse.
Chest discomfort

Especially new, severe, persistent, recurrent or associated with exertion or other warning symptoms.

Severe shortness of breath

Particularly when sudden, worsening, associated with chest discomfort or making normal breathing difficult.

Loss of responsiveness

Sudden collapse, unconsciousness or abnormal breathing may indicate cardiac arrest and requires immediate emergency response.

Do not drive yourself when you think you may be having a heart attack. Emergency medical services can begin assessment and treatment before arrival at the hospital.
Patient problem solver

Common CSMG problems and the fastest way to fix them

Your referral exists but CSMG cannot find it Ask the referring office for the authorization number, cardiologist name, destination fax and transmission date.
Your insurer says CSMG is covered but the office says no Compare the exact product, IPA, medical group, physician and location. “Aetna,” “Blue Cross” or “Cigna” alone is not enough.
You were assigned Perris or Montclair Confirm whether the appointment is virtual. Both are currently labeled telehealth-only on the detailed CSMG location page.
You are unsure which cardiologist to choose Give the scheduler the actual diagnosis: arrhythmia, valve disease, blocked artery, heart failure, vascular disease or preventive evaluation.
You need records from another cardiologist Complete CSMG’s Medical Release Authorization early enough for the prior office to send the records before the consultation.
You cannot log into the portal Start again from CSMG’s official FollowMyHealth link and confirm that your account is connected to the correct medical record before creating another account.
You were told to prepare for a stress test but received no instructions Call the testing office before changing caffeine intake, food or medications. Preparation differs by test type.
You received a large self-pay estimate Ask what portion belongs to the physician, facility, imaging, device or other service and request a written Good Faith Estimate when eligible.
Inland Empire patient shortcuts

Practical tips that can prevent repeat visits and scheduling delays

01
Bring the actual medication list

Cardiology treatment often depends on exact dose and frequency, not simply the drug category.

02
Know your IPA

California HMO referrals may depend as much on the assigned medical group as the insurance company.

03
Confirm telehealth status

Perris and Montclair are currently listed as telehealth-only.

04
Send old cardiac testing first

Prior echo, stress, monitor and catheterization reports can help avoid unnecessary duplication.

05
Bring your device card

Patients with pacemakers or other implanted cardiac devices should keep identification available.

06
Ask which site performs the test

Your office visit and procedure may occur at different facilities.

07
Do not assume office hours

Corona and Beaumont have narrower schedules than Riverside, Murrieta, Temecula or Hemet.

08
Keep home measurements

A dated blood-pressure, pulse and symptom log can make follow-up decisions more useful.

09
Ask for the next step before leaving

Know who will contact you with results, what symptoms require earlier attention and when follow-up is expected.
