Changes in hemodynamics before and after pulmonary vein isolation. Atrial fibrillation led to deterioration of hemodynamics as shown by the decrease in blood pressure and in urine volume. Pulmonary vein isolation restored sinus rhythm and successfully improved hemodynamics. Solid arrows indicate electrical cardioversion to terminate atrial fibrillation; dotted arrows indicate electrical cardioversion to terminate ventricular tachycardia. CHDF = continuous hemodiafiltration; IABP = intraaortic balloon pump.
