WebOct 25, 2016 · Answer. The ECG shows sinus rhythm with premature ventricular contractions (PVCs) in a pattern of bigeminy. The PVC morphology is left bundle branch block with a late precordial R wave transition (QS-wave V1 and V2 to R-wave in V3) and inferior axis (positive R waves in II, III, avF) consistent with a right ventricular outflow … WebMar 11, 2024 · The ECG axis. The QRS axis represents the major vector of ventricular activation, which is the overall direction of electrical activity. ... There are shortcut methods to determine the axis. For example, if the QRS complex is upright in both leads I and II, then the axis must fall somewhere between -30º and 90º and the axis is normal. clientrowset
