Ventricular dyssynchrony is a condition wherein there is no synch or difference in the timing of contractions in different ventricles in the heart. Large differences in timing is often correlated with heart failure as it can reduce cardiac efficiency.
Types of dyssynchrony
- Atrioventricular (AV) dyssynchrony: difference in timing between atrial and ventricular contractions
- Interventricular dyssynchrony: difference in timing between right ventricular (RV) and left ventricular (LV) Systole
- Intraventricular dyssynchrony: timing in a sequence of activations and contractions of segments of the LV wall becomes abnormal
Intraventricular dyssynchrony occurs when the timing in a sequence of activations and contractions of segments of the LV wall becomes abnormal.
These changes in timings lead to changes in the dynamic behavior of the myocardial tissues which leads to mechanical dyssynchrony.
