The PR interval in ECG denotes?: (A) Atrial depolarization only, (B) Atrial depolarization with A - V conduction, (C) Ventricular depolarization and ventricular repolarization, (D) Atrial depolarization with atrial repolarization
Answer is B. Atrial depolarization only - P- Wave Ventricular depolarization and ventricular repolarization - QT interval
