Patent ID: 7684862

Claim:
A method for delivering a therapy to terminate a tachycardia event, comprising: sensing cardiac signals and detecting the tachycardia event in response to the sensed cardiac signals; delivering a first plurality of pacing pulses in response to the detected cardiac event; determining a return cycle length generated subsequent to the delivery of the first plurality of pacing pulses; determining whether the return cycle length is greater than a cycle length associated with the tachycardia event and less than a sum of the cycle length associated with the tachycardia event and a total prematurity associated with the first plurality of pacing pulses; and adjusting delivery of a second plurality of pacing pulses in response to the return cycle length not being greater than the cycle length associated with the tachycardia event and less than the sum of the cycle length associated with the tachycardia event and the total prematurity associated with the first plurality of pacing pulses.
