Electrocardiogram
An electrocardiogram (ECG) records the electrical activity of your heart and is an essential tool to assess heart rhythm, detect arrhythmias (irregular heartbeats), and provide your doctor with a clear view of how your heart’s electrical system is functioning.
Why it’s used: It helps identify conditions such as atrial fibrillation, heart block, conduction delays, or other rhythm‐related issues that may require further evaluation or treatment.
How long it takes: The test is very quick — only a few minutes while you lie down, electrodes are applied to your chest, arms and legs, and the recording is captured.
How to prepare: No special preparation is required. You may eat and drink normally and should take your usual medications unless instructed otherwise. Wear comfortable clothing and remove any upper‐body jewelry or heavy garments so electrodes can be placed comfortably.
What to expect: A technologist will place small stickers (electrodes) on your chest, arms and legs, ask you to relax and breathe normally, then record your heart’s rhythm. You’ll return to your normal routine immediately afterwards.
Results & follow‐up: The ECG recording is reviewed by your cardiologist and results are forwarded to your family doctor for discussion with you.
