PROCEDURES
STRESS ELECTROCARDIOGRAM
A stress electrocardiogram or ECG, is done to record the electrical signals produced by the heart under stress, to determine what level of stress may affect the hearts ability to function properly.
WHY DO I NEED IT?
You cardiologist may want to perform a stress ECG can determine how much stress the heart can handle before the blood flow to your heart muscle is affected or an abnormal rhythm begins. An electrocardiogram or ECG, is a test done to record the electrical signals produced by the heart’s chambers. When this test is done during a stress test, it is known as a stress electrocardiogram.
HOW IS IT DONE?
Before the stress echocardiogram electrodes will be stuck to your chest and your cardiologist will measure your heart’s electrical activity and rhythm while at rest. You will then exercise on a treadmill or stationary bicycle for between 6 and 10 minutes while the electrodes monitor your blood pressure and electrical heart rhythms. The exercise will become progressively harder over time until you are exhausted. At regular intervals, the lab personnel will ask how you are feeling. Any chest pain, dizziness and weakness you experience during the test should be communicated to your cardiologist. After the test, you will cool down for a couple of minutes. Your electrocardiography will continue to monitor your heart rate until your heartbeat returns to normal.
WHAT ABOUT AFTERWARDS?
After the stress ECG your doctor will have a look at the results recorded during the test. Dr van Rensburg will then be able to identify if and when electrical impulses changed and be able to diagnose an abnormality with your heart’s structure, rhythm, rate and blood supply. Further testing may then be necessary to plan treatment.
