1 You are on a ride along in an EMS vehicle. A person has been pulled from an icy river after being submerged for at least ten minutes. Someone attaches a heart monitor which shows organized waveforms and a very slow heart rate (roughly 10 beats per minute). The airway has been suctioned and is clear. No pulse or breathing is detected. Which of the following do you suspect?

8 You administer a defibrillation dose (200 J biphasic) to the patient and continue CPR. After two minutes, you check the pulse and rhythm. The patient returns to sinus bradycardia (30-bpm) and there is a faint, but definite pulse present. Blood pressure is 80/30 mm Hg. He is still unconscious. What is your next action?
