Ventricular Dyssynchrony and Function Improve following Catheter Ablation of Nonseptal Accessory Pathways in Children

Figure 4

Determination of time-velocity curves using color-coded tissue Doppler and Q-analyses (from left ventricular septal and lateral wall sample points selected in an apical long-axis view). In this example (patient no. 6), no significant delay is demonstrated between septal and lateral left ventricular walls following catheter ablation.
