    Streszczenie angielskie: Background. Atrial fibrillation (AF) is the most common sustained tachyarrhythmia, which results in a 20 p.c. to 30 p.c. reduction in stroke volume and cardiac output in normal individuals. Although there were a large number of echocardiographic studies that focused on left ventricular function, right ventricular function has not been widely studied before and after cardioversion of AF. Aim. The aim of this study was to investigate the potential effects of carioversion on right ventricular function in patients with AF by tissue Doppler echocardiography. Methods. Fifteen patients with electrocardiographic evidence of AF 3 weeks duration and 12 age- and sex-matched healthy controls were included. Right ventricular systolic and diastolic functions were determined by conventional and tissue Doppler echocardiography before, 24 hours and one month after successful cardioversion of AF. Results. One month after restoration of sinus rhythm, left and right atrial dimensions significantly decreased in patietns with AF (p 0.01 and p 0.05, respectively). Heart rate decreased significantly already after 24 hours (p 0.01) and one month later remained significantly slower than during AF (p 0.01). Right ventricular filling parameters determined by conventional echocardiography improved after cardioversion. In the tissue Doppler echocardiography, the peak systolic velocities measured at the lateral corner of the tricuspid annulus were significantly lower in AF patients than in controls (p 0.001), whereas after cardioversion significantly increased...
