P wave is due to:
Answer is A (Atrial Depolarization) P wave is produced due to atrial depolarization. Intervals Events in the Hea During Interval P wave Atrial depolarization PR interval Atrial depolarization and conduction through AV node QRS duration Ventricular depolarization and atrial repolarization QT interval Ventricular depolarization plus ventricular repolarization ST interval (QT minus QRS) Ventricular repolarization
