OBJECTIVES. The aim of this study was to determine whether electrical or pharmacological cardioversion affects the coagulation system of patients with paroxysmal atrial fibrillation (PAF). Design. 35 Pati&nts with PAF undergoing either electrical or pharmacological cardioversion (CV) to sinus rhythm were studied. INTERVENTION. All patients underwent either electrical or pharmacological CV; the sinus rhythm was restored in all of them, and maintained throughout the observation period. MAIN OUTCOME. Fibrinopeptide A (F.p.A) and dDimer blood samples were taken immediately before cardioversion, and also within 5 minutes, at 6 and 12 hours post cardioversion. Blood samples were taken again at day 7. 14 and 28. RESULTS. When compared to the Control Group, the pre-cardioversion F.p.A plasma values were significantly elevated (11.8 vs. 2.5 ng/mL). F.p.A plasma values were significantly reduced 5 minutes after cardioversion (11.8 vs. 5.3 ng/mL), and remained stable at all the following sequential measurements. D-dimer plasma values were significantly increased only in patients who underwent electrical cardioversion. A positive correlation was found (R*=0.76) between the energy delivered for cardioversion to sinus rhythm and day-7 D-dimer plasma values. CONCLUS/OiVS. This study demonstrates that in patients with PAF the haemostatic system is activated; cardioversion to sinus rhythm rapidly normalises the haemostatic system. Electrical, but not pharmacological, cardioversion induces an early activation of the fibrinolytic system. The intensity of such activation depends upon the energy required to restore the sinus rhythm.
