Electrocardiography (ECG or EKG) is the process of recording the electrical activity of the heart over the skin. These electrodes detect the tiny electrical changes on the skin that arise from the heart muscle's electrophysiologic pattern of depolarizing during each heartbeat. This record is called the electrocardiogram (otherwise called an ECG), which gives data about the piece of the heart that triggers every heartbeat (the pacemaker called the sino-atrial hub), the nerve conduction pathways of the heart, and the pulse and cadence.
Echocardiography is alluded to as cardiovascular reverberate delivered by the ultrasound waves which thusly make the pictures of the heart.
