SMART DELAY FOR INTERMITTENT STRESS THERAPY |
摘要 |
A pacing system delivers cardiac protection pacing to protect the heart from injuries. The pacing system receives a set of inputs and calculates parameters for delivering optimized cardiac protection pacing tailored for different stress levels. The system automatically adjusts heart rate to optimize cardiac protection pacing in a closed-loop system. In one embodiment, a method for delivering pacing pulses for cardiac protection is provided. Intrinsic atrioventricular (AV) intervals are sensed. The intrinsic AV interval and a predetermined equation relating the AV interval to an optimal AV delay are used to provide a maximum positive rate of left ventricular pressure change during systole. An AV delay is calculated using a predetermined percentage of the optimal AV delay to deliver ventricular pacing pulses to provide a desired level of stress for cardiac protective pacing therapy (CPPT) to provide a cardiac conditioning therapy to improve autonomic balance.
