Stress Testing – A stress test can evaluate the heart during exercise and is often more revealing than a test conducted at rest. A stress test can help diagnose coronary artery disease (CAD), high blood pressure, vavular disease and arrhythmias.  It can also evaluate cardiovascular physical fitness and measure the heart’s response to medical or interventional treatments. There are several types of stress tests:

  • Nuclear Stress Test (NST)– During a nuclear stress test, a small amount of radioactive substance is used to create a nuclear image that shows how well blood flows into the heart muscle, both at rest and during activity.
  • Exercise Stress Test – This test examines the heart’s activity using continuous electrocardiographic monitoring while exercising on a treadmill.

Echocardiogram (Echo) – An echocardiogram uses ultrasound (or sound waves) to examine the heart’s chambers and valve function. It is sometimes used with a stress test to provide additional information needed to help diagnose coronary artery disease, high blood pressure, valve disease, arrhythmias and others. Audio and visual recording of the waves rebounding from the heart walls and valves indicate the size, shape, texture and function of these structures. The speed and direction of the blood flow also can be evaluated.

Electrocardiogram (EKG) – An EKG is used to evaluate the electrical activity of the heart to identify evidence of a current or previous heart attack. Electrodes (small plastic patches) are placed at certain locations on the chest, arms and legs. The patches are connected by wires to a machine that interprets the heart’s electrical signals.

Holter Monitor Testing – A holter monitor is a machine that continuously records the heart’s rhythm during normal activity to detect coronary artery disease and arrhythmias.   The monitor is a battery-powered recording device with a strap that is worn over the shoulder or around the waist for 24-48 hours. The holter monitor has three wires (also known as leads) that attach to electrodes. The electrodes are placed on the chest to record the heart’s electrical impulses. The impulses are recorded for 24 hours and then reviewed by a physician.

Carotid Doppler Study – A carotid doppler study is a test that uses sound waves to create pictures of the blood flow in the two large arteries in your neck which are called the carotid arteries. You have one carotid artery on each side of your neck which supply your brain with blood.
