Clinical variables affecting recovery of left atrial mechanical function after cardioversion from atrial fibrillation.
OBJECTIVES We sought to evaluate the effect of clinical factors on recovery of atrial function after cardioversion for atrial fibrillation. BACKGROUND Lack of effective mechanical atrial function (EMAF) after cardioversion of atrial fibrillation predisposes to thromboembolic complications and delays improvement in functional capacity. METHODS Fifty-two patients underwent cardioversion (grou...
متن کاملConcomitant recovery of atrial mechanical and endocrine function after cardioversion in patients with persistent atrial fibrillation.
OBJECTIVES The purpose of this study was to evaluate left atrial mechanical function recovery and plasma atrial natriuretic peptide (ANP) release following successful cardioversion of persistent atrial fibrillation (AF). BACKGROUND Atrial fibrillation is characterized by functional deterioration, loss of atrial contraction, and elevation of plasma ANP levels. The response of ANP release towar...
متن کاملLeft ventricular diastolic function after electrical cardioversion of atrial fibrillation.
In chronic atrial fibrillation (AF) left ventricular function may gradually diminish as a result of an intrinsic tachycardiomyopathy. This tachycardia induced cardiomyopathy is characterised by decreased systolic function, ventricular dilation, and raised ventricular filling pressures. In such patients left ventricular systolic function may gradually improve after electrical cardioversion. Litt...
متن کاملAtrial and ventricular function after cardioversion of atrial fibrillation.
OBJECTIVE Previous studies on atrial recovery after cardioversion of atrial fibrillation have not taken into account new knowledge about the pathophysiology of transmitral and transtricuspid flow velocity patterns. It is possible to shed further light on this problem if atrioventricular inflow velocity, venous filling pattern, and atrioventricular annulus motion are recorded and interpreted tog...
متن کاملPulsed Doppler evaluation of atrial mechanical function after electrical cardioversion of atrial fibrillation.
Full recovery of atrial mechanical activity may not occur immediately after successful electrical cardioversion of atrial fibrillation to sinus rhythm. To examine the time course of recovery of left atrial mechanical function, serial two-dimensional, M-mode and transmitral pulsed Doppler echocardiographic studies were performed in 21 patients after elective direct current cardioversion of atria...
