Abstract
A method and device for delivering anti-tachycardia pacing (ATP) therapy that includes an electrode to sense cardiac signals and to deliver the therapy, sensing circuitry, electrically coupled to the electrode, to detect the tachycardia event in response to the sensed cardiac signals, and a processor to control delivery of the therapy. The processor determines whether a return cycle length generated subsequent to the delivery of a first plurality of pacing pulses is less than or equal to a cycle length associated with the tachycardia event, and adjusts delivery of a second plurality of pacing pulses in response to the return cycle length being less than or equal to the cycle length associated with the tachycardia event.
Claims22
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 less than or equal to a cycle length associated with the tachycardia event;
- and
- adjusting delivery of a second plurality of pacing pulses in response to the return cycle length being less than or equal to the cycle length associated with the tachycardia event.
A medical device for delivering a therapy to terminate a tachycardia event, comprising:
- an electrode to sense cardiac signals and to deliver the therapy, the therapy including a first plurality of pacing pulses;
- sensing circuitry, electrically coupled to the electrode, to detect the tachycardia event in response to the sensed cardiac signals;
- and
- a processor to control delivery of the therapy, wherein the processor determines whether a return cycle length generated subsequent to the delivery of the first plurality of pacing pulses is less than or equal to a cycle length associated with the tachycardia event, and adjusts delivery of a second plurality of pacing pulses in response to the return cycle length being less than or equal to the cycle length associated with the tachycardia event.
