Abstract
Mitral valve prolapse is the most common heart disease seen in college and university health services. It underlies most arrhythmia and many chest pain complaints. Auscultatory findings vary; only 60% have the click, only 48% have the murmur, and in half of those with murmur, it was heard better at the upper-left sternal border than at the apex. In 15%, neither click nor murmur was heard. Only two patients had major arrhythmia. Endocarditis prophylaxis is indicated. Activity and exercise restrictions are usually unnecessary.
