Cardiology is the medical specialty devoted to caring for everything related to your heart and circulation. The industry has made great progress in diagnosing and treating heart disease. Though age is a contributing factor, the single most important cause of heart disease is unhealthy lifestyle.

When it comes to heart disease, prevention is the best medicine. Even if you have a family history of heart disease, living a healthy lifestyle is the key to preventing heart problems. Whether you’re an adult with congenital heart disease or an athlete seeking a cardiac evaluation before you play a sport, our cardiologists address your unique needs with a highly personalized, integrative approach to cardiovascular care that includes individualized assessments, advanced diagnostic services and therapies for the prevention and treatment of cardiovascular disease. Most importantly, we encourage you to adopt healthful lifestyle habits for meaningful longevity and quality of life. The good news is that heart disease can be discovered early - or even prevented altogether – if you get regular checkups and heart screenings.

What heart conditions do Stamford Health cardiologists treat?

Advanced cardiac diagnostic testing and procedures at Stamford Health:

Our diagnostic procedures are performed with the highest standard of care and state-of-the-art technology to obtain the best results and maximize your comfort and convenience. These procedures are typically painless and allow you to resume your normal activities almost immediately:

  • Cardiac event recorder monitoring: A battery-powered portable device that allows you to record your heart’s electrical activity when you have symptoms.
  • Electrocardiogram (ECG or EKG): A test that measures your heart’s rate and rhythm.
  • Holter and event monitoring: A portable EKG monitor that measures your heart’s electrical activity continuously for a period of 24 to 48 hours.
  • Ambulatory blood pressure monitors: A small machine that records your blood pressure every 15 to 30 minutes.
  • Transthoracic echocardiography (TTE): An echocardiogram that uses ultrasound waves to map a picture of your heart and arteries by moving a transducer over your chest.
  • Transesophageal echocardiography (TEE): An echocardiogram that uses ultrasound waves to create images of your heart and arteries. The transducer is attached to a thin tube that passes through your mouth, down your throat and into your esophagus.
  • 3D echocardiography: An echocardiogram that provides a three-dimensional, detailed anatomical view of your heart and arteries, which can reveal problems such as valvular defects and cardiomyopathies.
  • Stress (exercise tolerance) echocardiography: An echocardiogram that is performed while you are exercising on a treadmill or stationary cycle to measure your heart’s blood supply and rhythm.
  • Stress (exercise tolerance) test: A test that measures your heart's blood supply and rhythm while you are exercising on a treadmill or stationary cycle.
  • Nuclear perfusion cardiac imaging: A procedure that uses nuclear medicine to evaluates your heart’s function and blood flow.
  • Tilt table test: A test to determine the cause of fainting episodes due to an abnormal drop in blood pressure and heart rate. In this test, you lie down on a table that moves from a lying down to an upright position while your symptoms, heart rate, EKG reading and blood pressure are monitored.
  • Cardiac computed tomography (CT) and coronary CT angiography: X-ray imaging techniques that use a computer to produce cross-sectional images to examine your heart and blood vessels for problems.
  • Vascular ultrasound (e.g., carotid ultrasound): Ultrasound that evaluates your body’s circulatory system and help identify blockages and detect blood clots.
