SpletARVD is a form of cardiomyopathy with fibrofatty infiltration of the right ventricle, characterized by inverted T waves, ε waves, notched S wave, and widening of QRS (>110 ms) in the right precordial leads (V1-V3) (Fig. 25-8 ). 87 The signaled-averaged ECG usually is markedly abnormal.

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. indian facts for kidsSpletS Wave Amplitude.
