Abstract
The present invention provides methods and systems for tachyarrhythmia therapy involving pacing the heart to prior to the application of a cardioversion/defibrillation shock. One or more pace pulses are delivered to the arrhythmic chamber or chambers. The pace pulses may be delivered to the heart at an adaptable rate selected to organize the electrical activity of the heart. If the pace pulses produce capture, cardioversion/defibrillation stimulation is delivered.
Claims60
A method for providing cardiac therapy, comprising:
- delivering pace pulses to an atrium of a heart during a tachyarrhythmia episode;
- detecting capture of the atrium associated with at least one of the pace pulses;
- and
- delivering cardioversion/defibrillation stimulation to the atrium responsive to the detection of capture.
A method for providing tachyarrhythmia therapy to a heart, comprising:
- delivering pace pulses to the heart during a tachyarrhythmia episode;
- detecting capture of the heart associated with at least one of the pace pulses;
- and
- delivering cardioversion/defibrillation stimulation responsive to the detection of capture.
A system for delivering therapy to a heart, comprising:
- a lead system, the lead system comprising electrodes and extending into the heart;
- pulse generator circuitry coupled to the lead system, the pulse generator circuitry configured to generate pulses to electrically stimulate the heart;
- a detector system, the detector system coupled to the lead system and configured to sense cardiac signals transmitted through the lead electrodes;
- and
- a control system coupled to the detector system and the pulse generator, the control system configured to control the generation of pace pulses during a tachyarrhythmic episode, to detect capture associated with at least one of the pace pulses, and to control delivery of a cardioversion/defibrillation stimulation responsive to the detection of capture.
A therapy system, comprising:
- means for delivering pace pulses to an atrium of a heart during a tachyarrhythmia episode;
- means for detecting capture of the atrium associated with at least one of the pace pulses;
- and
- means for delivering cardioversion/defibrillation stimulation to the atrium responsive to the detection of capture.
An system for providing therapy to a heart, comprising:
- means for delivering pace pulses to the heart during a tachyarrhythmia episode;
- means for detecting capture associated with at least one of the pace pulses;
- and
- means for delivering cardioversion/defibrillation stimulation responsive to the detection of capture.
