¶ 2 patients had ICDs (for non-ischemic cardiomyopathy and
neurocardiogenic syncope, respectively), 14 had pacemakers only, and 1
had no available data on device type.
Table 3: Operative Characteristics. For patients that had
follow-up of at least 6 months or longer postoperatively, operative
characteristics were compared across postoperative rhythm outcomes.
There were no significant differences between groups by freedom from
versus recurrence of ATAs for any of these variables (alpha = 0.05).
