Key result
Model 0072 leads are linked to ~94% higher postshock electrogram amplitudes during persistent VF vs model 0062.
Why the study?
Does the redesigned defibrillator lead model 0072 prevent postshock attenuation of endocardial electrogram amplitudes compared to the previous model 0062 in patients receiving defibrillators?

May support redesigned leads to lessen postshock sensing issues; leaves open effects on VF redetection and outcomes.

The redesigned defibrillator lead model 0072 shows significantly less postshock attenuation of endocardial electrogram amplitudes compared to the older model 0062, potentially reducing the risk of failure to redetect ventricular fibrillation.
Jung et al. (1995) conducted an observational in Ventricular fibrillation (n=26). Redesigned lead system model 0072 vs. Previous lead model 0062 was evaluated on Endocardial electrogram amplitude during redetection of ventricular fibrillation (p=0.0006). The redesigned lead system model 0072 demonstrated significantly less postshock attenuation of endocardial electrogram amplitudes during persistent ventricular fibrillation compared to model 0062 (6.6 vs 3.4 mV, P=0.0006).
