title: Electrocardiographic responses to maximal exercise during acute pericarditis and early repolarization.
abstract: Exercise testing is contraindicated during active pericarditis because of the possibility of myocarditis. In a patient suspected of having ischemic heart disease, a pericardial rub appeared for the first time following a maximal exercise test, during which the elevated J-points descended to baseline. In two normal volunteer subjects with early repolarization during a maximal exercise test, the elevated J-points behaved similarly. We conclude that, contrary to previous belief, electrocardiographic exercise responses cannot distinguish between pericarditis and early repolarization.
