Figure 2From: A modified echocardiographic protocol with intrinsic plausibility control to determine intraventricular asynchrony based on TDI and TSI Receiver operating characteristic curve analysis was used to further evaluate the longest intraventricular delay, i.e., the delay between the segments with the shortest and longest AVO-S' interval. A cut-off of 50 ms had a sensitivity of 94% and specificity of 93% to discriminate control and LBBB patients.Back to article page
