Abstract
Official abstract text for this publication.
Pacing pulses are delivered to one or more cardiac regions to improve diastolic performance in patients having diastolic dysfunction and/or heart failure. A cardiac pacing system executes a pacing algorithm using a parameter indicative of the diastolic performance as an input. The pacing pulses excite the one or more cardiac regions to redistribute the loading on the ventricular wall during diastole, thereby improving the diastolic performance by lowering the degree of cardiac wall motion dyssynchrony associated with diastolic dysfunction.
First claim
Opening claim text (preview).
What is claimed is: 1. A method, comprising: predicting an effectiveness of delivering pacing pulses to improve a measure of diastolic performance, wherein predicting the effectiveness includes: recording a left ventricular echocardiogram; dividing a left ventricular endocardial wall into multiple regions; measuring left ventricular regional endocardial wall displacements over at least one cardiac cycle for each of the regions using the recorded left ventricular echocardiogra…
