Non-Invasive Diagnostic Procedures

Electrocardiogram (EKG)

An EKG is a non-invasive cardiac test to evaluate the electrical activity of the heart. It provides information about a person’s heart rate, rhythm, blood supply to the heart and possible structural abnormalities of the heart. The results of an EKG are printed out on a graph for the physician’s interpretation.

Holter Monitor

A holter monitor is used to detect irregular, fast or slow heart rhythms. A patient wears the small, battery-operated recorder for 24 to 72 hours of normal activity. Electrodes attached to the patient’s chest connect to the recorder, which collects EKG information for 24 hours. A cardiovascular specialist later analyzes the full 24 hours of data on a computer and prints the results for the physician to interpret.

Specialty Holter Monitoring
30 Day Event Monitor - Your physician may feel you need to wear a holter monitor for more than 24 – 72 hours to make sure any suspected arrhythmias are recorded. The 30 day event monitor allows you to transmit your rhythm activity to the physician as many times as necessary during the 30 days by using a simple telephone line. This monitor can be taken off for bathing. At the end of the test, the event monitor is mailed back to the hospital in a self-addressed envelope that is provided to the patient.

Stress Test

A stress test is also known as a cardiac stress test, exercise EKG, exercise tolerance test or a treadmill. It is performed to help physicians detect heart problems that may not be apparent when the heart is at rest. The patient walks on a treadmill to increase their heart rate, and information is recorded before, during and after walking. The results give information on how well blood is able to flow to the heart muscle and helps determine the probability of coronary artery disease.

Nuclear Stress Test
This is a type of Stress Test where special images are taken before and after exercise. These images show areas of the heart that may not be receiving enough blood flow due to coronary artery disease.

A radioactive substance such as thallium or sestamibi is given through an IV site during a predetermined time, usually near the time of peak exercise. Once the substance is given, the patient lies under a camera for approximately 20 – 30 minutes.

Usually, a patient will have to lie under the camera two times, once at rest (either before exercise or an hour or so after exercise) and once immediately after exercise while the heart rate is still up.

Invasive Diagnostic Procedures

Cardiac Catheterization

Left and Right Heart Catheterizations are minimally invasive procedures that your Cardiologist can use to determine the presence of coronary artery atherosclerosis (blockage), assess abnormalities in the hearts muscle function (infarction or cardiomyopathy), measure the intracardiac pressures, and determine how well the heart valves function. Based on these results, treatment options will be discussed with you by your


Also known as a cardiac ultrasound exam. An echo procedure uses ultrasonic sound waves that move through the body tissue to the heart. The sound waves form images of the inside of the heart showing its valves, chambers, and movement. Echo also uses a technique called color doppler to view blood flow and blood flow velocity through the heart. This procedure may be ordered to evaluate heart-related signs and/or symptoms. It is performed in the Echo Laboratory.

Specialty Echocardiograms
Stress Echo – This is an echocardiogram that is performed in conjunction with a stress test.

Transesophageal Echocardiogram – This is an invasive procedure where the probe, or transducer, is placed down the patient’s esophagus in order to view more difficult to obtain images of the heart. Because patients are given a mild sedative for this test, they may not drive the remainder of the day after it is completed.
