title: [A new sock and snap electrode for epicardial mapping].
abstract: Simultaneous recording of epicardial activation from multiple sites during anti-arrhythmic surgery is essential to determine the location of the arrhythmic source. We formed a new sock from Presnet tubular dressing material with 87 snap electrodes. Bipolar recording sites, 1.0 mm in diameter and separated 1.5 mm, are constructed of gold and attached to steel wire directly at the male snap without button. This new Sock and Snap electrode was used to record in 7 patients; 5 of WPW syndrome and 2 of non-ischemic ventricular tachycardia. Satisfactory epicardial contact was obtained in all patients without any hemodynamic change. We could get a rapid display of epicardial mapping using a computer.
