Abstract
The invention provides an implantable medical device system and method for determining when a patient is undergoing a sudden rate drop (SRD) that should be treated by intervention therapy. Two SRD detection algorithms are provided. A first algorithm is a rate-based algorithm that looks for rate drops that meet stored SRD criteria, and a second algorithm is a QT-based algorithm that detects when QT variations meet criteria that are associated with rate changes characteristic of onset of NMS. The system provides for a plurality of different intervention pacing therapies that are selected based on which detection algorithm, or both algorithms, indicate SRD. The priority of choice of algorithms is programmable.
