What is ECG?
ECG is a test which evaluates any problems with the electrical activity of heart. The spikes and dips in the tracings are called waves. It is done in patients in case of symptoms such as dyspnoea (difficulty in breathing), chest pain (angina), fainting, palpitations or when someone can feel their own heart beat. An ECG can be used to assess if the patient has had a heart attack or evidence of a previous heart attack. It can also be used to reveal rhythm problems such as the cause of a slow or fast heart beat, thickening of heart muscle etc.
