PROGNOSTIC SIGNIFICANCE OF BUNDLE BRANCH BLOCK IN ACUTE CORONARY SYNDROME.

BACKGROUND: Cardiovascular disease has now become the leading cause of mortality in India. The primary cause of death in most of the developed nations is CHD, despite improvements in diagnostic and therapeutic procedures. The electrocardiogram's left bundle-branch block could mask the alterations caused by MI which delays the management. MAIN TEXT AIMS AND OBJECTIVES: To understand the significance of bundle branch block. To estimate the incidence of bundle branch block and its prognosis in acute coronary syndrome. PATIENTS AND METHODS: A prospective analytical study was done on 150 patients over 18 months with patients with angina chest pain admitted to the coronary care unit. Patients with known bundle branch block and previous coronary artery disease are excluded from the study results Right bundle branch block may occur normally in healthy individuals but when it is associated with acute coronary syndrome it indicates poor prognosis compared to the left bundle branch block.
