Figure 1: Diagram illustrating the intervals of interest in assessment of dyssynchrony using Pulse Wave Doppler technique. Top; Blue arrow indicates right ventricular preejection interval, Red arrow indicates left ventricular preejection interval, while black arrow indicates interventricular mechanical delay. Bottom; electrocardiogram tracing to give corresponding electrical activity of the heart
