Spotlight practices rotate daily among the most complete profiles — nobody pays for a spotlight. Featured practices pay for their placement; it is always labeled “Featured” and shown here, separately from the directory listings and nearby practices. Neither is a recommendation or a ranking, and neither changes directory order or the facts on any profile. Nearby practices are shown by their relative location, and directory lists put the most complete profiles first — see our standards.

Arizona is home to 93 verified cardiologists across 15 cities, with plans like Aetna, Cigna, and AHCCCS (Medicaid) widely accepted. Every listing is checked against the federal NPI registry. No paid ranking — paid placements are always labeled Featured.
Cardiology practices handle the diagnosis and management of heart disease — including hypertension, arrhythmias, heart failure, and coronary artery disease. Services typically include EKG, stress testing, echocardiograms, and ongoing medication management. Most patients are referred by their primary care physician, often after concerning symptoms or screening results.
Cardiology in Arizona — frequently asked questions
Real questions Arizona patients ask — from finding the right practice and understanding insurance to costs, visits, and when to seek care.
City Select lists 93 verified cardiologists across 15 Arizona cities. Every listing is matched against the federal National Provider Identifier (NPI) registry, so you're seeing real, registered practices — not paid placements.
38 cardiologists in the directory list Medicare. Use the insurance filter to narrow by Medicare, AHCCCS (Arizona Medicaid), Aetna, Cigna, UnitedHealthcare, Blue Cross Blue Shield, and more — counts update for the city you choose.
Pick your city from the search bar or filter rail to see cardiologists in that area — the directory covers Phoenix (22), Chandler (14), Mesa (14), Scottsdale (13), Gilbert (8). You can also search by practice name, doctor name, insurance, or service to build a shortlist in seconds.
Yes. Every profile is sourced from the federal NPI registry maintained by CMS, and we never sell ranking. Listing order is determined by how complete a practice's verified profile is (services, providers, insurance, hours) — never by payment. Featured and sponsored placements are always clearly labelled as such and never change the directory order, a practice's verification status, or any fact on its profile. A practice can improve its position by claiming its listing and adding information — for free.
Consider a cardiologist for symptoms like chest discomfort with exertion, unexplained shortness of breath, ongoing palpitations, dizziness or fainting, or swelling in the legs and ankles — or if you have risk factors like high blood pressure, high cholesterol, diabetes, or a strong family history of heart disease. Sudden chest pain, severe shortness of breath, or fainting needs emergency care now.
Not always, but treat it seriously. Call 911 right away for chest pain or pressure lasting more than a few minutes, or pain spreading to the arm, jaw, or back with shortness of breath, sweating, or nausea — these can signal a heart attack. Milder, recurring chest discomfort still deserves prompt evaluation by a doctor.
Often, yes — many cardiology offices and HMO/POS insurance plans require a referral from your primary care doctor, while most PPO plans don't. Either way, talking to your PCP first is useful, since they can run initial tests and point you to the right specialist.
Your primary care doctor manages overall health and can handle routine heart-risk issues like blood pressure and cholesterol. A cardiologist is a heart specialist for diagnosing and treating heart and blood-vessel conditions, ordering advanced testing, and managing complex or ongoing cardiac care — usually after a referral.
Common tests include an EKG (a quick recording of the heart's electrical activity), an echocardiogram (a painless ultrasound of the heart, about 20 minutes), and a stress test (monitoring your heart during exercise). Your cardiologist chooses tests based on your symptoms and history.
Your cardiologist reviews your history and symptoms, checks vitals and listens to your heart and lungs, examines you for signs of fluid buildup, and often runs an EKG that day. Bring a list of symptoms (and when they occur), your medications, and any family history of heart disease.
Occasional fluttering or skipped beats are often harmless and tied to caffeine, stress, or lack of sleep. See a doctor if palpitations are frequent, last a long time, or come with dizziness, chest pain, or shortness of breath — and seek emergency care if they're accompanied by fainting or severe symptoms.
Costs vary widely: an EKG is relatively inexpensive, while echocardiograms and stress tests can run from a couple hundred to a few thousand dollars without insurance, and an initial office visit often runs $200–$500. Most plans cover medically necessary cardiac care, but confirm coverage — a covered visit doesn't always mean every test is automatically covered.
Cardiologists diagnose and manage high blood pressure, high cholesterol, coronary artery disease, heart rhythm problems (arrhythmias), heart failure, valve disease, and more — and they help prevent heart disease in people with risk factors. Surgical cases are referred to a cardiac surgeon.
A cardiologist diagnoses and treats heart conditions with medication, procedures, and lifestyle management, and oversees ongoing care. A cardiac (or cardiothoracic) surgeon performs operations like bypass or valve surgery. Cardiologists handle most heart care and refer to a surgeon only when an operation is needed.
Yes — while your primary care doctor often manages these day to day, a cardiologist can step in for harder-to-control or high-risk cases, fine-tune medications, and assess your overall cardiovascular risk to prevent heart attack and stroke.
No — both are painless and non-invasive. An EKG uses small stickers on your skin to record your heartbeat in a few minutes, and an echocardiogram uses an ultrasound wand with gel on your chest, much like a pregnancy ultrasound, taking around 20 minutes.
It's worth discussing with your doctor. If you have high blood pressure, high cholesterol, diabetes, smoke, or have a strong family history of early heart disease, a primary care or cardiology evaluation can catch problems early and guide prevention — even before symptoms appear.
It depends on your condition and how stable it is — some people are seen every few months, others once or twice a year. Your cardiologist sets the schedule based on your diagnosis, medications, and test results.
Medicare Part B covers medically necessary cardiology visits and tests like EKGs, echocardiograms, and stress tests, and you typically pay 20% of the approved amount after your deductible. Some preventive cardiovascular screenings are also covered; confirm specifics with your plan.
Bring a list of your symptoms (including when they happen and how long they last), all current medications and doses, your medical and family heart history, and any recent test results or records. Specifics — like when palpitations or chest discomfort occur — help your cardiologist pinpoint the cause.
