In recent years abundant information has been obtained about the relationship of heart disease and cardiac late potentials. Non-invasive recordings of ventricular late potentials are useful in risk stratification of various clinical conditions, in particular, in patients following myocardial infarction. Here a close correlation has been established between cardiac late potentials and spontaneous or induced sustained ventricular tachycardias using programmed electrical stimulation. Cardiac late potentials also appear to be associated with arrhythmic events in patients with cardiomyopathies, and following unsuccessfu1 antitachycardia surgery. Furthermore, recording of abnormal late potentials are associated both with acute rejection after cardiac transplantation and unsuccessful thrombolytic therapy after myocardial infarction. Interestingly, antiarrhytmic drugs have no clear effect on cardiac late potentials.
