Key result
Epicardial impedance evaluation revealed lower impedance in low voltage areas without fat compared to those with fat (164 ± 69 Ω vs. 248 ± 89 Ω, P=0.002), helping identify effective ablation sites.

Does epicardial impedance evaluation differentiate between epicardial fat and myocardial tissue in patients undergoing epicardial VT ablation?
p-value: p=0.002
Real-time epicardial impedance evaluation can differentiate between adipose tissue and myocardial tissue, potentially guiding more effective epicardial VT ablation sites.
Kitamura et al. (2017) conducted an observational in Ventricular tachycardia (n=7). Epicardial impedance evaluation vs. Epicardial fat was evaluated on Impedance difference between epicardial fat and epicardial low voltage area (p=0.002). Epicardial impedance evaluation revealed lower impedance in low voltage areas without fat compared to those with fat (164 ± 69 Ω vs. 248 ± 89 Ω, P=0.002), helping identify effective ablation sites.
