Stress Tests

A stress test, sometimes called a treadmill test or exercise test, helps your doctor find out how well your heart handles its workload.

Electrocardiogram (EKG)

Electrocardiography is the process of recording the electrical activity of the heart over a period of time using electrodes placed over the skin.

An electrocardiogram, or EKG for short, is performed to detect problems or possible concerns within the heart. An EKG is a non-invasive, painless test that records the electrical signals within the heart. There are several different kinds of EKG’s, one’s that we offer include a Holter monitor, event monitor and treadmill test. A Holter monitor is a wearable device that records continuous EKG between 24 and 48 hours, while an event monitor is used only during certain times in intervals of several minutes.

Stress Echo

A stress echocardiography, also called an echocardiography stress test or stress echo, is a procedure that determines how well your heart and blood vessels are working. During a stress echocardiography, you’ll exercise on a treadmill or stationary bike while your doctor monitors your blood pressure and heart rhythm.

Nuclear Thallium Scan

A thallium stress test is a nuclear imaging test that shows how well blood flows into your heart while you’re exercising or at rest. This test is also called a cardiac or nuclear stress test. The radioisotope will flow through your bloodstream and end up in your heart. [RADIOISOTOPE: used minimally during this test and is not harmful to the body and not harmful around others.]

Our nuclear studies include:

  • MUGA is a diagnostics test used to observe circulation within the lower chambers of the heart

  • Treadmill stress utilizes a small solution to observe blood flow to the heart as well as its overall functionality

  • Chemical stress studies are performed to witness how well the heart functions when it’s under stress

PET Stress

A PET scan of the heart is a noninvasive nuclear imaging test. It uses radioactive tracers (called radionuclides) to produce pictures of your heart. Doctors use cardiac PET scans to diagnose coronary artery disease (CAD) and damage due to a heart attack.
