Effect of an irregular ventricular rhythm on cardiac output

Am J Cardiol. 1996 Dec 15;78(12):1433-6. doi: 10.1016/s0002-9149(97)89297-1.


Impairment of cardiac function in atrial fibrillation has been attributed to loss of atrial contraction and to a rapid ventricular rate. The results of this study suggest that irregularity of the ventricular rhythm, independent of the ventricular rate, may also contribute to impairment of cardiac function during atrial fibrillation.
