title: Extrasystole: Runners' Normal Abnormality.
abstract: During a routine physical I was found to have an irregular heart beat. I am a runner who trains at a round 25 miles a week, and I feel fine, but now my doctor wants me to go through a series of tests. In the meantime he advised me to stop running. The alternative is to take drugs, which I don't care to do. What do you advise?
