From: Exercise-induced left bundle branch block and subsequent mechanical left ventricular dyssynchrony -resolved with pharmacological therapy

Figure 2

Speckle tracking radial time strain curves derived from a mid-left ventricular short-axis image with left bundle branch block after treadmill exercise test. Significant mechanical dyssynchrony is indicate by the time difference (white arrow) of 260 ms between time-to peak strain in the anterior septum (red line) and to posterior wall peak strain (green line).
