Why is the pause after the PVCs relatively long? We see a sinus arrhythmia in the rhythm strip. The ventricular extrasystoles penetrate the AV node retrogradely and reset the sinus rhythm, which then restarts. VA conduction can be recognized by the inverted P wave following the QRS complex of the ventricular extrasystole (PVC).
