What is the principle of ECG

An electrocardiogram (ECG) is one of the humblest and fastest examinations used to assess the heart. Electrodes (minor, plastic covers that stick to the skin) are positioned at certain spots on the torso, arms, and legs. The electrodes are linked to an ECG machine made by ECG Machine Manufacturers by lead wires. The electrical activity of the heart is then calculated, understood, and printed out. Natural electrical instincts synchronize contractions of the diverse parts of the heart to keep blood flowing the way it should. An ECG done on equipment supplied by ECG Machine Suppliers records these instincts to show how fast the heart is beating, the pace of the heart beats (stable or uneven), and the strength and phasing of the electrical instincts as they transfer through the diverse parts of the heart. Variations in an ECG done on equipment bought from ECG Machine Dealers can be a sign of many heart-related disorders.
