Classification: CPC A | IPC A

Claim 0:
1. A system comprising:
a stimulation generator configured to deliver electrical stimulation to a patient;
a sensing module configured to sense activity of the patient's heart; and
a processor coupled to the sensing module and configured to:
anticipate a ventricular tachyarrhythmia in a heart of a patient based on the ventricular tachyarrhythmia not yet being detected but a counter reaching a threshold value of a ventricular tachyarrhythmia event count;
determine a sense time period; and
in response to anticipating the ventricular tachyarrhythmia, control the stimulation generator to deliver electrical stimulation to block the atrioventricular node of the heart over an electrical stimulation delivery time period, wherein the electrical stimulation delivery time period is based on the sense time period over which ventricular depolarizations can be sensed during the electrical stimulation delivery time period, the electrical stimulation delivery time period being bounded by limits that prevent an accumulation of blanking periods applied to a sensing amplifier that would exceed the sense time period.
