Abstract

Arrhythmias are common complications in myocardial infarction (MI) patients and significantly impact Emergency Department (ED) outcomes. However, regional data on arrhythmia profiles in North India's MI patients are lacking, necessitating a comprehensive investigation. Methods: A prospective observational study was conducted over ten months, assessing MI patients' arrhythmias at ED presentation in a tertiary care hospital. Inclusion criteria encompassed MI diagnosis, and exclusion criteria comprised certain pre-existing arrhythmias and incomplete data. Demographics, clinical characteristics, arrhythmia types, and ED outcomes were recorded. Results: Among 78 MI patients analyzed, diverse arrhythmias were observed, including atrial fibrillation, sinus brady/tachycardia, and ventricular arrhythmias. A correlation between specific arrhythmias and adverse outcomes was noted, highlighting the importance of tailored management strategies. However, limitations such as sample size and single-center nature were acknowledged. Conclusion: The study underscores the significance of characterizing arrhythmia profiles in MI patients at ED presentation. Understanding these profiles could inform risk stratification, personalized interventions, and improved management strategies. Multicenter studies are warranted to validate findings and refine guidelines.
