NettetLeft ventricular dyssynchrony (LVD) is common in heart failure patients with LV systolic dysfunction. Contrary to what it could be expected, LVD is not a stable phenomenon. … Three chief presentations of dyssynchrony can occur: Atrioventricular (AV) dyssynchrony occurs when there is an unfavorable difference in timing between atrial and ventricular contractions. Interventricular dyssynchrony occurs when there is a difference in timing between right ventricular (RV) and left ventricular (LV) Systole.
