Graph and trace
Continuation of the tachycardia; modification of the programming with shortening of the post-ventricular atrial blanking (vertical line); the second atrial signal is now sensed in the PVARP (AR); the filtered atrial interval quickly reaches the switching threshold; DDIR mode and progressive deceleration of the ventricular pacing rate toward the sensor rate.
