Non-PV foci. a: An electrocardiogram from a 68-year-old man after cryoablation of PAF. After ISP administration, the earliest PAC from the ostium of the coronary sinus induced AF. b: Multipolar catheter caught the earliest potentials at the CS ostium (red arrow). In this patient, an electric current applied to the posterior wall of the CS ostium caused the PAC to disappear and AF was not induced. PV: pulmonary vein; PAF: paroxysmal atrial fibrillation; ISP: isoproterenol; AF: atrial fibrillation; PAC: premature atrial contraction; CS: coronary sinus
