Our Approach

After the tests are completed, a physician will discuss the results, options and next steps with you. Never hesitate to share questions or concerns. When it comes to your health, you are the most important member of our medical team.

Non-invasive cardiovascular testing

Our staff of dedicated health care professionals will work with you to determine the diagnostic tool appropriate for your unique situation.

  • Angiography — visualizes and diagnoses coronary artery disease. The physician injects a special dye (contrast dye) into the coronary arteries and a series of X-rays are taken that show the location and extent of coronary artery narrowing or obstruction. This procedure is usually performed via an artery in the groin
  • Echocardiography — creates images of heart and blood vessel structure and function using high-frequency sound
  • Electrocardiography — records the electrical activity of the heart
  • Holter monitoring — a continuous recording of your heart rhythm, usually for 24 hours, while you go about your daily activities. This is especially useful in diagnosing abnormal heart rhythms
  • Positron emission tomography (PET) — non-invasive imaging that can reveal the health of the vessels supplying blood to the heart and surrounding tissue
  • Stress testing — measures how the heart works during stress or exercise
  • Exercise stress test — usually involves walking on a treadmill or pedaling on a stationary bike at increasing levels of difficulty while your electrocardiogram, heart rate and blood pressure are monitored
  • Stress echocardiography — combines stress testing with echocardiography for additional information on cardiac structure and function
  • Nuclear stress test — measures blood flow to your heart muscle both at rest and during stress on the heart and is performed in a similar fashion to a routine exercise stress test. This test provides images that show areas of low blood flow through the heart and areas of damaged heart muscle
