Study of arrythmias within 48 hours of Acute Coronary Syndrome

Abstract

Introduction: Acute coronary syndrome remains the leading cause of mortality in the industrialized world. Development of arrhythmia during the early period of ACS leads to majority of deaths. Study was aimed seeing retrospectively the occurrence of arrhythmias within 48 hours of ACS. Method: We did an observational study on 200 patients from April 2019 to June 2020 in our department via fulfilling the criteria. Results: Maximum number  of patients were in the age group 60-69 years. Arrhythmias were more common among male. Most common arrhythmia was ventricular premature complex (23.5%) followed by 1^st degree AV block (11%). Majority of arrhythmia (51.5%) occurred within 6 hours of hospitalization. Conclusion: Most of the arrhythmias develops during initial 24hours of ACS with almost half of these occurred within 6 hours of onset of symptoms. Mortality is more common in patients with arrhythmias specifically QRBBB, VT and CHB.
