Atrial Fibrillation and Ventricular Dysfunction

Left ventricular diastolic dysfunction in atrial fibrillation

Atrial fibrillation and ventricular dysfunction: a vicious electromechanical cycle.

Case Presentation: A 44-yearold man with a history of hypertension presented with New York Heart Association class IV congestive heart failure (CHF) and atrial fibrillation (AF) with rapid ventricular response (160 beats per minute) and unknown onset. Transthoracic and transesophageal echocardiography demonstrated severe global left ventricular (LV) dilatation, LV ejection fraction (LVEF) of 20...

Atrial Fibrillation and Ventricular Arrhythmias

Circulation. 2017;135:593–608. DOI: 10.1161/CIRCULATIONAHA.116.025312 February 7, 2017 593 Anne M. Gillis, MD ABSRACT: Sex-specific differences in the epidemiology, pathophysiology, clinical presentation, clinical treatment, and clinical outcomes of atrial fibrillation (AF), sustained ventricular arrhythmias, and sudden cardiac death are recognized. Sex hormones cause differences in cardiac ele...

Ventricular response to atrial fibrillation.

The result of the management of the seven cases of cardiac tumors reported by Bini et al. (I) was quite discouraging as only one child survived 3 months. In a recent review of cardiac tumors reported in the English language between 1972 and 1977 (2), I found 47 reported pediatric cases with a survival rate of more than 6 months in 55% of the cases. Forty-four of these tumors were benign with a ...

Ventricular dynamics in atrial fibrillation.

During atrial fibrillation there are beat-to-beat changes of ventricular rate, end-diastolic volume, end-diastolic pressure, and arterial pressure or resistance to ventricular ejection. The effect of these variables on left ventricular dynamics in man has been approached by studying single sequences of beats in patients with atrial fibrillation. An index of changes of left ventricular volume ha...
