Figure 3From: Rescue pulmonary vein isolation for hemodynamically unstable atrial fibrillation storm in a patient with an acute extensive myocardial infarction Pulmonary vein isolation. A: Baseline intracardiac electrograms of the right pulmonary veins before isolation during atrial fibrillation. B: Intracardiac electrograms of the right pulmonary veins after isolation. Sinus rhythm was restored by an electrical cardioversion following isolation of the right pulmonary veins. C: Baseline intracardiac electrograms of the left pulmonary veins before isolation during pacing from the distal bipoles of coronary sinus. D: Intracardiac electrograms of the left pulmonary veins after isolation. E: Three-dimensional map (NavX, St. Jude Medical) with white dots representing RF ablation lesions. LAA = left atrial appendage; RIPV = right inferior pulmonary vein. Other abbreviations as in Figure 2.Back to article page
