High defibrillation thresholds are encountered in some patients during
implantation of the automatic implantable cardioverter defibrillator
(AICD). In a consecutive series of 52 patients with AICD implants, 46 had
allepicardial implants by left subcostal thoracotomy, and 8 of these
patients had thresholds greater than 30 J. Placement of an apicolateral
large left ventricular patch and an extrapericardial large right atrial
patch electrode through a limited right thoracotomy produced substantial
reduction in their thresholds. Especially in patients who have had previous
intrapericardial operations, this technique provides a simple solution to
the problem of high thresholds.
