WebThe slow spread of the impulse will result in a slow (and abnormal) activation of the right ventricle, which yields a bizarre and prolonged QRS complex on ECG. The hallmark of right bundle branch block is QRS duration ≥0,12 seconds, large R'-wave in V1/V2 and a broad and deep S-wave in V5/V6. Figure 2 illustrates a normal ECG, a right bundle ... 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. tarek jbihaWebTerminal activation duration (TAD), defined as the interval between the nadir (lowest point) of the S-wave and the end of the depolarization, is prolonged (>55 ms in V1-V2).
