Abstract

The cause of severe cardiac conduction disturbances is often uncertain. The aim of this study was to examine a group of patients with permanent pacemakers who underwent coronary arteriography to determine the extent of coronary atherosclerotic disease that might be responsible for the conduction disturbances. Forty-three consecutive patients with a permanent pacemaker and 36 matched control patients were investigated. The coronary angiographic study included measurement of diameter and stenosis severity, qualitative assessment of flow, and classification of pathological anatomy, particularly the blood supply to territories supplying the different segments of the conduction system. Among 43 patients with a permanent pacemaker, 27 had ischemic heart disease (17 after coronary artery bypass graft surgery). The conduction disturbance was infranodal in 28 patients, sinus nodal in 6, AV nodal in 4, and complete AV block of unspecified origin in 5. Patients with permanent pacemakers had a coronary artery pathology compromising blood flow to the septal branches and the right coronary artery (type IV anatomy). This pattern was significantly different from the matched control patients, in whom the most prevalent coronary anatomy was the ...Continue Reading
