Dr Paul Wang:                   Welcome to the monthly podcast, On the Beat, for Circulation: Arrhythmia, and Electrophysiology. I'm Dr Paul Wang, Editor-in-Chief, with some of the key highlights from this month's issue.                                                 Koji Miyamoto and associates conducted the AD-Balloon Study, which investigates the ideal number of free cycles during second-generation cryoballoon pulmonary vein isolation. In a prospective, multicenter, randomized clinical trial, the authors compared in 110 patients the addition of a three minute freeze after pulmonary vein isolation had been achieved to pulmonary vein isolation alone. Delayed-enhancement magnetic resonance imaging was also performed one to two months after the pulmonary vein isolation to assess the ablation lesions. The freedom from atrial arrhythmias at one year was similar. Log rank test, P equals 0.78 in the two groups, 87.3% in the extra three-minute freeze group, and 89.1% in the pulmonary vein isolation group. There w
