[Role of electric stimulation of the heart during selective contrast examination of the coronary arteries with the use of the data of continuous recording of the bundle of His potentials and arterial pressure].
The frequency of disorders of the cardiac rhythm during injection of a contrast medium into the coronary vessel under different conditions was studied in 214 patients. Atropine premedication was applied as a preventive factor in 142 patients, atrial stimulation in 60, and both factors simultaneously in 12. In 10 patients a single injection of the contrast medium was performed without preventive measures. In 20 patients the changes were studied by recording the potentials of the bundle of His and the arterial pressure. On the basis of the bundle of His ECG data it is concluded that atropine and atrial stimulation produce an effect on individual links of the complex mechanism underlying the effect of the contrast medium on the cardiac conduction system.
