My68 year old husband just had a syncopal episode. He was out for about 10 seconds. He is otherwise healthy, exercises regularly. He has a normal heart rate of approximately 55-60. This happened one other time about 18 years ago. We are not at home. We are about 5 hours from our home. The plan is to call his regular physician in the morning and return home. Any suggestions in the meantime.

Summarized question: How can a syncopal episode be treated?
