Abstract
Exercise testing with continuous monitoring and recording of the electrocardiogram has proven to be a very useful tool for the diagnosis of coronary insufficiency in the presence of a typical chest pain or in coronary patients with normal resting ECG, which happens in about one-third of the cases. A satisfactory sensitivity of about 60% (i.e. about 40% of false negative results) is obtainable (1), especially if loading is sufficiently heavy, if ECG is recorded during the test as well as during the recovery period and if analysis takes into account not only the quantitative amount of ST changes but also the speed at which the ST segment comes back from the J point to the baseline (5). Moreover, specificity is at least 90% (i.e. about 10% of false positive results) (1) if some well known factors influencing ECG response to exercise, e.g. digitalis or electrolyte disturbances, are recognized.
