Large differences in timing of contractions can reduce cardiac efficiency and is correlated with heart failure.
Intraventricular dyssynchrony occurs when the timing in a sequence of activations and contractions of segments of the LV wall becomes abnormal.
[2] All three presentations allow distinct and easily reproducible electrical signatures as illustrated by left and right bundle branch blocks, hemiblocks, etc.
[1] Once again the terms inotropy and chronotropy apply to the pathology under examination.
Biventricular pacing strongly favors chronotropy over inotropy.
