Non-invasive Cardiovascular Testing

These studies use instrumentation that remains outside the body, such as the traditional x-ray or MRI. Other methods used to gain precise information include:

  • Electrocardiogram (EKG) - A printed record of the electrical activity of the heart, used to detect abnormal heart rhythms.
  • Signal average EKG - A specialized EKG test that may be used for patients who are susceptible to sudden irregular heartbeats.
  • Stress testing - Heart rate, blood pressure and EKG responses are collected during exercise to evaluate the heart's response.
  • Echocardiogram (ECHO) - A color image of the heart using sound waves, which reveals abnormalities of heart muscles or valves and fluid around the heart. We also offer stress and pediatric echocardiography.
  • Transesophageal echocardiogram (TEE) - Looks at the heart from inside the esophagus.
  • Holter monitoring and scanning (adult and pediatric) - Patients wear a small monitor at home, which tracks any abnormal rhythms.
  • Tilt Testing - Evaluates how changes in posture may affect blood pressure and heart rhythm.
  • Arterial, Venous and Carotid Doppler Studies - Sound waves detect blockages, abnormal pressure and blood clots in the various blood vessels.
