["Coronary arteriographic findings in the patients of arteriosclerotic heart disease combined with cardiac arrhythmias or conduction defects" (author's transl)].

Correlation between cine-coronary arteriographic findings and various cardiac arrhythmias or conduction defects were studied in 40 patients with arteriosclerotic heart disease. These cases were divided into 3 groups according to the type of arrhythmias or conduction defects. The following conclusions were drawn. 1. In the group I of 25 patients whose arrhythmias were atrial origin, there were sinus bradycardia in 9, suins tachycardia in 5, atrial premature beats in 2 and atrial fibrillation in 9. Cine-angiographically, the degree of luminal stenosis of the main coronary arterial branches were mild to moderate in severity compared to that of the other two groups. However, it was remarkable that the sinus node artery was not visualized in 9 of 25 cases (36%). 2. The group II of 5 patients who have shown premature ventricular contractions exhibited moderate to severe degree of stenosis of coronary artery trees, especially much more often in left anterior descending coronary arteries. 3. In the group III of 10 patients who had various type of intraventricular conduction defects, the degree of stenosis of the main coronary artery branches were usually severe and also, the number of the coronary artery involved in stenosis was increased. Interestingly, atrioventricular node arteries were not opacified in 5 of 10 cases. There were 2 cases of complete A-V block where the atrioventricular node artery was not visualized at all both either from right or left coronary artery opacification. It seemed to be hard to draw a clear cut correlation between cine coronary angiographic pictures and a certain type of cardiac arrhythmias or conduction defects in such a small scale of study. However, cind coronary angiography may contribute to rule out local ischemia of the conduction tissue as a primary cause of the development of arrhythmias or conduction defects in patients with arterisclerotic heart disease.
