Cardiology-Cardiovascular Lab


The best way to fight heart disease is to find it in its earliest stages when it’s most treatable. Our on-site cardiovascular lab performs a variety of noninvasive tests to accurately diagnose and evaluate heart disease.

Our lab provides the following tests and procedures to study both the condition and function of the heart, arteries, and veins:

  • Transthoracic Echocardiogram (TTE) adult and pediatric – An echocardiogram is a test that uses ultrasound waves to examine the heart. Because it is a noninvasive test, it is a safe and painless way to help doctors diagnose a number of abnormalities of the heart.
  • Venous Doppler (upper and lower extremities, and venous insufficiency studies) – A venous Doppler is a diagnostic ultrasound test used to check the circulation in the veins of the legs or arms. This exam shows any blockage in the veins by a blood clot or “thrombus” formation. Blood clots can break loose and reduce or stop the flow of blood to the lungs. This is a dangerous condition known as pulmonary embolism. This procedure is painless and doesn’t require any preparation.
  • Arterial Doppler (upper and lower extremities, and physiologic arterial studies) – An arterial Doppler is an ultrasound test that looks at the blood circulation in the arteries to see if there is any blockage or reduction of flow.
  • Carotid Doppler – This ultrasound test is done to evaluate blocked or reduced blood flow in the arteries of the neck that could cause stroke. This test is also used to evaluate possible stroke symptoms, such as dizziness, vision changes and loss of balance.
  • Exercise Stress Test – A study that gathers information about how your heart works during physical activity and evaluates the presence of coronary artery disease. Our lab provides treadmill stress testing as well as non-treadmill stress testing using Lexiscan (a pharmacologic stress test option for those unable to exercise adequately or complete a treadmill exercise stress test). Myocardial Perfusion Imaging (MPI) or Cardiolite can be done in conjunction with the treadmill or non-treadmill stress test; it utilizes nuclear imaging to increase the sensitivity (accuracy) of the test.
  • Holter Monitor – A holter monitor is a machine that continuously records the heart’s rhythms. The monitor is worn for 24 hours during normal activity. Electrodes (small conducting patches) are stuck onto your chest. These are attached by wires to a small recording monitor. You carry the holter monitor in a pocket or pouch.
