title: Evaluation of the clinical electrophysiological effects of antianginal drugs without specific antiarrhythmic properties.
abstract: The authors have studied the electrophysiological effects of four antianginal drugs: oxyfedrine, nifedipine, dipyridamole and carbochromene. These drugs demonstrated different and sometimes contrasting effects on sinus node function, atrial refractoriness and atrioventricular conduction. These effects may constitute an indication or a contraindication in different clinical pictures and should be considered in the choice of treatment of patients with coronary artery disease.
