Diazepam was administered intravenously in doses of 10 to 40 mg to 18 consecutive patients who underwent 21 elective, direct-current countershock procedures for ventricular or supraventricular arrhythmias. Hypnosis lasting 15 to 30 minutes with complete amnesia for the event was induced on 20 occasions. One patient remained semiconscious and did recall three shocks up to 400 w/sec. No significant changes in heart rate, blood pressure, or respiratory rate were noted following administration of diazepam. The drug is safe, and it has enhanced the simplicity of the entire procedure.
