From: Fusion beat in patients with heart failure treated with left ventricular pacing: may ECG morphology relate to mechanical synchrony? A pilot study

Figure 8

The TDI asynchrony index (Ts-SD-12-ejection) did not vary significantly between each of the different steps and the value recorded during LBBB, but it showed a decreasing trend at AV1, AV2 and AV3. The mean value of Ts-SD-12-ejection corresponding to AV1, AV2 and AV3 reached statistical significance compared to the LBBB pattern with >18% improvement.
