What is ECG?
An electrocardiogram or electrocardiograph (ECG) is a simple, painless test which measures the rhythm and electrical activity of your heart. It really is very straightforward: sensors are attached to your skin to record your heartbeat in wave-form on a graph, which is printed out on paper for the doctor to read.
