Coronary performance was evaluated in 18 men and 6 women by i.v. infusion of increasing doses of isoproterenol and minute-by-minute ECG monitoring. The results appeared fully reliable. In some cases where the conditions for effort testing were satisfied a comparison was made with the cycle-ergometer findings. This shown the ISP test to be more precise, more sensitive and easier to perform technically.
