Sudden death in racquet sports.

The regular playing of racquet sports tends to confer general health and to protect the heart--to produce the athletic heart syndrome. Strenuous play, however, can provoke ventricular arrhythmias and can kill individuals with heart disease. The overall risk for an exercise death from racquet sport play seems to be as low as from distance running. Middle-aged men, however, especially those with known coronary disease or coronary risk factors, should approach racquet sports with caution, and might benefit from timely medical advice.
