From: Strain dyssynchrony index determined by three-dimensional speckle area tracking can predict response to cardiac resynchronization therapy

Figure 4

Bar graphs showing comparison of rates of response to cardiac resynchronization therapy (CRT). Patients with strain dyssynchrony index with area tracking (ASDI) ≥ 3.8% showed a response rate of 100% (7/7), those with 2-D radial dyssynchrony determined by speckle tracking strain ≥ 130 msec a rate of 82% (9/11), those with interventricular mechanical delay (IVMD) 40 ≥ msec a rate of 67% (6/9), and those with a Yu index ≥ 32 msec a rate of 62% (8/13) CRT.
