    Main Results:

    • Standard electroplate positioning is recommended, with specific considerations for patients with pacemakers.
    • An initial defibrillatory shock of 200 J is suggested for ventricular fibrillation.
    • Transthoracic impedance significantly impacts low-energy shock success rates but is less critical for high-energy shocks.

    Conclusions:

    • Optimizing electrical therapy delivery is essential for managing cardiovascular emergencies.
    • Proper electrode placement and appropriate energy selection are key to successful defibrillation.
    • Understanding transthoracic impedance is vital for effective low-energy defibrillation strategies.
