Abstract :

Acute myocardial infarction(AMI) is now a days leading cause of mortality n morbidity with increasing prevalence worldwide. Heart block is a disturbance of impulse conduction occurs due to Ischemic injury in acute myocardial infarction.Incidence is more common in older people and male, as AMI is more common in male.In western countries sedentary life style and obesity are more common while in our country smoking is the commonest risk factor.Hypertension and DM are also emerging risk factors.Most patients presents with chestpain,gabharaman and perspiration.Anteriorwall MI is commonly associated with intraventricular conduction block,while inferior wall MI is associated with atrio–ventricular nodal block. Though comlete heart block(CHB) is more common in inferior wall MI on presentation,anterior wall MI with trifascicularblock or RBBB+LPHB progress to CHB and mortality is high in those patients.Risk of cardiac asystole is more in CHB.Left ventricular failure and ventricular tachycardia can also increase the mortality particularly in anterior wall MI. In short, Heart blocks predict the poor outcomes.These patients are better responsive to thrombolytic therapy,angioplasty or pace maker insertion.So early detection and prompt management of these patients is required to reduses mortality and morbidity
