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 attached a heart monitor and states the patient's heart rate is very slow (roughly 10 beats per minutes) with discernible, but abnormal waveforms. The airway has been suctioned and is clear. There is no pulse or breathing. 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?
