Abstract:
1. A method for use with an implantable medical device for detecting ventricular dyssynchrony, the method comprising: sensing an electrical cardiac signal within the patient in which the device is implanted; identifying a ventricular repolarization event within the electrical cardiac signal; evaluating a morphological feature of the repolarization event that is affected by ventricular dyssynchrony; detecting ventricular dyssynchrony within the patient based on the morphological feature of the repolarization event, wherein detecting ventricular dyssynchrony within the patient includes detecting ventricular dyssynchrony based on the presence of two or more peaks within an individual repolarization event; and evaluating a degree of severity of ventricular dyssynchrony within the patient based on the number of peaks within individual repolarization events.
