Electrocardiography (ECG) is the strategy for recordance of the electrical action of the heart over an era utilizing anodes put on the skin. These cathodes help in the identification of the moment electrical changes on the skin that emerge from the electrophysiologic example of heart muscle while depolarizing amid every pulse. This record called the electrocardiogram (otherwise called an ECG), gives data about the piece of the heart that triggers every pulse (the pacemaker called the sino-atrial hub), the nerve conduction pathways of the heart, and the heart rate and beat . As a rule, an ECG is acquired if a heart issue is suspected.
