Cardiac pacing system for prevention of ventricular fibrillation and ventricular tachycardia episode
First Claim
Patent Images
1. A system, comprising:
- a controller, connected to a sense and pulse delivery module, the controller receiving signals from one or more electrodes and providing pulse instructions for delivery of pulses to the one or more electrodes; and
an event window generator, connected to the controller, producing event windows for ventricular contraction events, the event windows each being a function of a plurality of intervals between ventricular contraction events and a ventricular rate trajectory,wherein the controller produces an instruction for providing a ventricular contraction following an event from which one of the event windows begins if a ventricular contraction event is not detected during the one of the event windows.

Abstract
A cardiac pacing system preventing short-long-short pacing sequences. The system providing pacing pulses where necessary. The system having dynamic event window generation to adapt to changes in heart rate. The event window adaptable to process a number of intervals. The system including provisions for other inputs, such as sensor and morphology detection. The system adaptable for single mode and dual mode applications. The system also applicable to long pause prevention in atrial pacing and ventricular pacing.
