Impact of shortening the blanking period to 8 weeks after PVI: Insights from COMPARE-CRYO using continuous rhythm monitoring
Early recurrences of atrial tachyarrhythmias (ERATs) after pulmonary vein isolation (PVI) are common. While many correlate to late recurrences (LRs), some do not. The impact of ERAT timing is difficult to assess with noninvasive Holter monitoring because of undersampling. The recommended duration of the blanking period (BP) was recently shortened from 90 days to 8 weeks.
