WebThis pattern corresponds to the electrocardiographic manifestations of predominant right atrial overload. No significant changes in the QRS duration were observed. Also the magnitude and spatial orientation of the maximum QRS vectors remained constant. The interval between the QRS onset and the maximum spatial magnitude of the T wave … WebA QRS duration of 120 ms (0.12 s) or more is required to diagnose a complete left bundle branch block. In addition to prolonged QRS duration, LBBB is characterized by deep and broad S-waves in leads V1 and V2 and … incos beni
