An electrocardiogram (ECG or EKG) is a test that measures the electrical activity of your heart. With each heart beat, an electrical impulse (or wave) travels through your heart. This wave causes the muscle to squeeze and pump blood from the heart. A doctor can determine if this electrical activity is normal or irregular. The positive result (an abnormal ECG) can be a sign of a number of different heart conditions.
An ECG might be ordered if a patient complains of chest pain, chest discomfort, palpitations, chronic fatigue, breathing difficulties, dizziness, etc.
Preparation for the Procedure
No special preparation is required. Just make sure that you take a shower before you come to the clinic. Do not forget to bring your health card and a list of medications with you.
In the examination room you’ll have to remove all clothes from the waist up. Our technologist will attach a number of electrodes – usually a total of 12 to 15 – to various locations on your body including your arms, legs and chest. The electrodes are connected to the computer to detect the electrical activity of your heart. The test is usually performed while you lie still. Results are recorded on graph paper and interpreted or read by your doctor or a technologist. The test usually takes 10 to 15 minutes.
