WebS Wave. S Waves follow R waves. They are the first negative deflection after the R wave. The length from the end of the S wave and the beginning of the T wave is the ST segment. This segment indicates the timeframe between ventricular depolarization and repolarization. It is the baseline of the cardiac cycle and is electrically neutral. WebThe ECG machine processes the signals picked up from the skin by electrodes and produces a graphic representation of the electrical activity of the patient's heart. The basic pattern of the ECG is logical: electrical activity towards a lead causes an upward deflection. electrical activity away from a lead causes a downward deflection.
