    Abstract:
    The endocardial manipulations and bolus intracoronary administration of contrast substances, of the first generation in particular, can induce disturbances of the myocardium repolarization and different disturbances of the cardiac rhythm, life-threatening included. The aim of the investigation is to assess transitory electrophysiological alterations in the myocardium during coronarography and during the first day after it. Under examination there were 39 patients with ischemic heart disease and stenocardia of the II-III functional classes in whom the coronarography was performed according to clinical indications. The Holtner dynamic observation of ECG was made in all the patients. All the ECG changes were detected and estimated during coronarography: arrhythmias, disturbances of conduction and transitory ischemic alterations of the myocardium. It gives a possibility to decide between the methods of pharmacological correction of possible disturbances.
