Key result
A dual coil defibrillation lead system showed no significant advantage over a single coil system for defibrillation thresholds at implantation (10.2 ± 5.2 J vs 10.3 ± 4.1 J, P=NS).
Why the study?
Does a dual coil defibrillation lead system improve defibrillation thresholds and lead parameters compared to a single coil system in patients with ventricular arrhythmias undergoing ICD therapy?

Absolute Event Rate: 10.2% vs 10.3%
p-value: p=NS
Dual coil defibrillation leads offer no significant advantage over single coil leads regarding defibrillation thresholds or lead parameters during ICD implantation.
Rinaldi et al. (2003) conducted an RCT in Ventricular arrhythmias (n=76). Dual coil defibrillation lead system vs. Single coil defibrillation lead system was evaluated on Defibrillation thresholds (DFT) at implantation (p=NS). A dual coil defibrillation lead system showed no significant advantage over a single coil system for defibrillation thresholds at implantation (10.2 ± 5.2 J vs 10.3 ± 4.1 J, P=NS).
