'I'm clear, you're clear, everybody's clear': a tradition no longer necessary for defibrillation?

摘要

In emergency defibrillation of ventricular arrhythmias or elective cardioversion of atrial arrhythmias, a potent electric shock is passed through the torso of the patient to briefly terminate all electrical activity and allow an organized, perfusing rhythm to emerge. The electric shock is administered via electrodes placed on the patient's chest, usually in anterior-apical or anterior-posterior positions. For many years, hand-held paddle electrodes were pressed by a rescuer against the patient's chest; more recently, pregelled self-adhesive electrode pads with nonconductive backing have achieved widespread use.
