The working principle of electrocardiogram (ECG) is based on the electrical activity of the heart. Electrodes are used to capture and transmit cardiac electrical signals to a recording device, which are then displayed graphically. 1
ECG records electrical signals generated by the heart during contraction and relaxation. These signals cause the excitement and contraction of myocardial cells through the conduction of cardiac tissue. In order to capture these electrical signals, ECG uses electrodes to capture and transmit cardiac electrical signals to a recording device. Usually, electrodes are placed at specific locations on the limbs and chest to record different directions and locations of cardiac electrical activity. When the heart contracts and relaxes, electrical signals propagate in the cardiac tissue. The electrodes capture these electrical signals and convert them into weak currents, which are then transmitted to the ECG recording device through wires. The ECG recording device amplifies the electrical signals and displays them graphically. This graph is usually displayed in the form of multiple waveforms, such as P waves, QRS complexes, and T waves.
