Abstract
Method and apparatus for preventing heart rhythm disturbances by recording cardiac electrical activity, measuring beat-to-beat variability in the morphology of electrocardiographic waveforms, and using the measured beat-to-beat variability to control the delivery of electrical impulses to the heart during the absolute refractory period.
Claims36
Method of preventing a heart rhythm disturbance comprising:
- detecting cardiac electrical activity;
- analyzing the cardiac electrical activity to measure beat-to-beat variability in the morphology of electrocardiographic waveforms;
- and
- delivering electrical impulses during a time interval after the R-wave and prior to the end of repolarization.
