WebThe QT-R-R relationship during exercise was studied in 52 patients. Forty-two patients had VT associated with a "clinically normal" heart (idiopathic VT), of which 23 had no VT on exercise and 19 had exercise-induced VT. These patients were compared to 10 subjects with exercise-induced VT related to ischemic heart disease.
