Three simulated scenarios conducted in this study. In scenario 1, an electrical shock was delivered to a patient isolated from the ground, with the rescuer making single-point contact (rescuer’s hands are on chest). In scenario 2, an electrical shock was delivered to a patient while both the rescuer and the patient were in contact with the common ground, and the rescuer made single-point contact with the patient (rescuer’s hands are on chest). In scenario 3, an electrical shock was delivered to a patient with the rescuer making contact at two different points (rescuer’s hands are on chest and their knee is also touching the patient). SIG, signal; COM, common.
