Three-dimensional echocardiography with left ventricular strain analyses helps earlier prediction of right ventricular pacing-induced cardiomyopathy.

Considering QRS duration, the odds of getting the event is 1.019 (0.994–1.046) as the duration progresses ( Table 2 ); meanwhile, other factors did not reach statistical significance: age ( p = 0.275), sex ( p = 0.630), QRS axis quadrant ( p = 0.161), QRS duration ( p = 0.143), change in QRS duration from baseline ( p = 0.471), site of pacing ( p = 0.500), and ventricular pacing threshold ( p = 0.410).
