There are at UHN:
An ECG records the electrical impulses moving through the heart muscle. The test won't cause you any pain, but you'll need to lie quietly for about 3 minutes. Wires will be attached to your chest, arms and legs. Electrical currents from your heart will go through the ECG machine and be recorded on special graph paper.
The ECG is used to measure the rate and regularity of heartbeats and can show an abnormal heartbeat, the presence of any damage or enlargement of the heart muscle. It can also show if your heart isn't getting enough oxygen and the effects of drugs or regulating devices.
The Patient & Family Education Program at UHN offers valuable resources to help you understand your condition.
