If you ever wondered about your heart health, you probably came across an ECG monitor and perhaps wondered how ECG testing or monitoring works

What is an ECG?

ECG is the abbreviation of the word electrocardiogram – a heart test that tracks the electrical activity of your heart and records it on a moving paper or shows it as a moving line on a screen.
