The classical and standardized method for exercise stress testing is to increase a work load of a bicycle ergometer or treadmill by stepwise increase method.This precedure somethimes provokes a non-stepwise increase in the myocardial oxygen consumption.We, therefore, have developed a new exercise stress testing method for subjects with myocardiaI ischaemia.The work loads of the ergometer in continuously adjusted so that a linear increase in the PRP(systolic blood pressure×heart rate)could be obtained.Using this method, three subjects performed exercise stress testing.The results produced good lineahties between the predicted PRP and actual PRP.It is suspected that this new-method might be safe and applicable to patients with ischaemic heart disease.
