Exercise-induced ventricular tachycardia.
Exercise tests were done on all patients referred to us because of ventricular premature beats. Exercise-associated ventricular tachycardia was seen in three of these patients. Once therapy for the arrhythmia was begun in two patients, we performed serial exercise tests, attempting to provoke the arrhythmia again. In the third patients, who was pregnant, we advised against strenuous physical activity and will exercise her post partum to determine whether therapy is warranted. We have shown that exercise testing can be used successfully in unmasking ventricular arrhythmias not detectable on resting evaluation.
