ECG is the Echocardiography of the heart activity. It measures/records the electrical activity of the heart by placing electrodes near the heart, legs, and arms. There are different electrode placement methods.
ECG includes the P wave, QRS complex, and T wave. Each wave corresponds to a particular activity/part of the cardiac cycle.
RR interval - the interval between two R waves is used for estimating the heart rate from the ECG.
The ECG is used for finding any abnormalities in heart activity.
