Key result
Chronic implantation of epicardial patch electrodes for 10-15 days achieved adequate defibrillation thresholds (mean 18 joules) in 100% of patients who initially failed testing.

Absolute Event Rate: 100% vs 0%
Chronic implantation of epicardial patch electrodes for 10-15 days allows for adequate defibrillation thresholds in patients with initially unacceptably high thresholds and hemodynamic instability during testing.
Grubb et al. (1991) conducted an observational in High initial epicardial patch defibrillation thresholds (n=6). Chronic implantation of epicardial patch electrodes vs. Initial implant (baseline) was evaluated on Adequate defibrillation thresholds. Chronic implantation of epicardial patch electrodes for 10-15 days achieved adequate defibrillation thresholds (mean 18 joules) in 100% of patients who initially failed testing.
