What is LV Asynchrony Analysis for CRT Optimization about?
This document describes a study that developed a computational algorithm to quantify left ventricular asynchrony throughout the cardiac cycle using tissue Doppler imaging echocardiography. The algorithm calculates the temporal matching between the septal and lateral wall movements. In 50 cardiac resynchronization therapy patients, the algorithm results agreed with the visually determined optimal ventricular pacing interval 94% of the time. Responders to CRT showed higher degrees of dyssynchrony compared to
