ECG, Electrocardiogram

Recording of the electrical activity of the heart. The heart is a pump activated by electrical power. These electrical potentials can be recorded by ECG. The standard ECG is recorded from 12 different points. These reference points are created by placing electrodes on the body surface surrounding the heart. The points are exactly defined and each electrode records the electrical progress from its point of view. The electrodes are commonly called leads. The standard ECG is a 12-lead ECG. ECG recording can detect various heart problems such as rhythm disturbances or signs of a heart attack. .
