[Cerebral circulatory disorders in patients with cardiovascular diseases accompanied by cardiac rhythm disorders].

The authors examined 180 patients where disorders of cerebral circulation developed on the background of different disturbance of the heart rhythm. The patients suffered from rheumatic heart disease, hypertensive disease or atherosclerosis in concomitance with ischemic heart disease. For comparison, 100 patients with similar disorders were studied, but without disturbances of heart rhythm. It was established that disorders of cerebral circulation were more frequently seen in permanent forms of cardiac fibrillation and less so in paroxysmal cardiac fibrillation and extrasystoles. The most severe disorders of cerebral circulation were seen in combinations of permanent forms of cardiac fibrillation with single and frequent ventricular extrasystoles in patients with rheumatic heart disease.
