A substantial number of patients with acute myocardial infarction have some cardiac rhythm abnormality, and approximately twenty-five percent have cardiac conduction disturbance within 48 hours following infarct onset. Almost any rhythm disturbance can be associated with acute myocardial infarction, including bradyarrhythmias, supraventricular tachyarrhythmias, ventricular arrhythmias, and atrioventricular block. Smoking (76%) and hypertension (23%) were the most common risk factors in the present study, followed by dyslipidemia (22%). The overall in hospital mortality in this study was 15 % - 10 were males (66.7%) and 5 were females (33.3%).
