Abstract:
1. In an implantable cardiac stimulation device, a system that automatically induces a tachyarrhythmia of a patient's heart, the system comprising: a pulse generator that generates a series of pacing pulses separated in time by predetermined pacing intervals to a desired chamber of the patient's heart, the series having a predetermined number of overdrive pacing pulses followed by a predetermined number of inducing pacing pulses; a sensing system that senses when a tachyarrhythmia has been induced; and a control circuit, coupled to the pulse generator and the sensing system, that automatically adjusts the pacing intervals between the inducing pacing pulses when a tachyarrhythmia has not been induced, and then automatically triggers the pulse generator to deliver a subsequent series of pacing pulses using the adjusted pacing intervals; wherein the control circuit is configured to automatically terminate the delivery of the series of pacing pulses to the patient's heart when a tachyarrhythmia has been induced.
