ABSTRACT:

Background and objectives: Arrhythmias remain an important cause of mortality in patients with inferior wall MI, despite significant progress. Most of these arrhythmias occur within the 1st twenty four hours. The objective of this study was to govern the type and time of onset of arrhythmia in patients with inferior wall acute myocardial infarction and its outcome. Study Design: A Prospective Study. Place and Duration: In the Department of Cardiology, NICVD Satellite Centre Hyder Abad for one year duration from January 2018 to January 2019. Methods: 120 consecutive patients with myocardial infarction were selected for the analysis. Risk factors for heart disease were assessed based on physical examination, blood tests and medical history. Patients were observed for arrhythmias for 48 hours after the onset of myocardial infarction. Arrhythmia type and time have been reported. Results: 48 out of 120 patients with myocardial infarction had cardiac arrhythmias. Age and gender did not have a statistically substantial consequence on the onset or type of arrhythmia. Most arrhythmias lasted for 1-12 hours, and complete heart block was the most common arrhythmia (40%). There was no statistically significant effect between smoking, alcohol, hypertension, diabetes, left ventricular dysfunction, thrombolysis and arrhythmias. Conclusion: It is concluded that people with inferior myocardial infarction and cardiac arrhythmias have high hospital mortality rate. Key words: Arrhythmias, acute myocardial infarction of the inferior wall, complete heart block, acute myocardial infarction, acute coronary syndrome.
