“…As noted by Cosby et al (1965) the presence or absence of previous myocardial infarction was the critical factor in determining prognosis and none of the other clinical or electrocardiographic indices were significantly related to long-term survival.…”

Between the years 1960 and 1974, 839 patients were paced for chronic complete atrioventricular block. Analysis of survival compared with the general population showed that 170 deaths were expected according to standard mortality tables and 288 actually occurred, giving a ratio of actual to expected deaths of 1.7:1. Patients with a definite history of myocardial infarction showed a higher than average mortality when paced. Mortality was not influenced whether heart was constant or intermittent, whether the ventricular rate was below or above 40/minutes, or whether QRS duration was greater or less than 0.1 second. Analysis of the age groups paced disclosed the most important correlations. Between the ages of 80 and 89 years paced patients could expect to survive as long as other of the same age without heart block. There was, however, a very high ratio of 4.5:1 for 90 patients in the age group 50 to 59 years. The reason for the high mortality ratio was uncertain but it may have been the result of a greater incidence of underlying coronary artery disease.

“…Electrocardiographic examination assists the diagnosis of CHB, pertaining to various features like atrial rate, ventricular rate, degree of variation of both atrial and ventricular rates, presence or absence of changing block and width of the QRS. 4 Normally, the AV node receives blood from either dominant Right Coronary Artery (RCA) or Left Circumflex Artery (LCX) and Left Anterior Descending (LAD) artery. 5 Moreover, usually the damage in AV node or his bundle is not due to the abnormality in proper AV node, but more probably due to obstruction in arteries that supply blood to AV node.…”

BACKGROUNDThe angiographic findings and prognosis of patients with Complete Heart Block (CHB) remain unclear. Thus, we aimed to study the clinical profile, risk factors, angiographic distribution and in-hospital outcomes of patients with complete heart block. MATERIALS AND METHODSThis was a prospective, single-centred study which included 100 patients who came to the emergency department with CHB. Routine blood investigations including serum electrolytes were done. Coronary angiogram was done and lesions were assessed. Temporary pacemaker was implanted followed by permanent pacemakers in required patients, and in-hospital complications were noted down. RESULTSCommonest age group was above 60 years (75%). The patients were predominantly males. Most common presentation was chest pain (60%); there was regional wall motion abnormality in 30% patients. Degenerative complete heart block was seen in 34% patients, diphtheric myocarditis in 15%, hypokalaemic in 15%, dilated cardiomyopathy in 2%. Of total 53 patients had AV block, 14 had bifascicular block, 23 had LBBB, 6 had RBBB, 3 had Mobitz I and 1 had Mobitz II. Inferior wall myocardial infarction (MI) was pervasively present in patients. Temporary pacemakers were implanted in 6 patients and permanent pacemakers in 43 patients. In-hospital outcomes constituted of complication like cardiogenic shock (10%) and death (26%). The patients who died either had 80% -90% stenosis in RCA, triple vessel disease, ostioproximal LAD occlusion or diphtheric myocarditis. CONCLUSIONComplete heart block was majorly associated with advanced age and inferior wall MI, virtually caused by dominant RCA occlusion. The in-hospital mortality was significantly higher in the patients with CHB.
