Implication

Animal correlations between field and current remain preclinical; leaves open human validation for defibrillation guidance.

Structured PICO

Population

25 anesthetized swine (8 for intracardiac location comparison, 5 for impedance correlation, 12 for ventricular fibrillation induction)

Intervention

Multiple electrode, catheter-based device for closed-chest 3D measurements of electric field from transthoracic defibrillation shocks

Outcome

Electric field measurements and their correlation with peak current and defibrillation successsurrogate

A novel catheter-based system can reliably measure intracardiac electric fields during transthoracic defibrillation, providing subject-specific information that correlates with shock success.
