The Electrocardiogram is a diagnostic test which produces a record of the overall spread of electrical activity through the heart. Electrical currents generated by your cardiac muscles spread into the tissues surrounding the heart and are conducted through your bodily fluids. An electrocardiogram uses recording electrodes to record the small portion of this electrical activity that reaches your body’s surface.
How to Prepare
Avoid applying lotion and skin creams on the day of the test as they may prevent the electrodes from sticking. Before your visit to our Vancouver Diagnostics Centre, your patient advisor will guide you and provide you with all the information you need to prepare for your Electrocardiogram.
What to Expect
During the exam, 12 recording electrodes will be placed on your chest in positions surrounding your heart. These electrodes are connected to the electrocardiogram machine. Your diagnostic technician will then review your electrocardiogram on a computer screen and print it out once they are happy with the quality of the test. The procedure takes a total of only 15 minutes.
