Clinical Correlation Between Inferior Vessel Occlusion and Arrhythmia Incidence in Acute Coronary Sundrome Patients

Background: Arrhythmia is a frequent acute complication in patients with Acute Coronary Syndrome (ACS) and significantly contributes to morbidity and mortality. Myocardial ischemia, autonomic imbalance, and structural myocardial injury lead to electrical instability that may trigger supraventricular and ventricular arrhythmias. Local data evaluating the relationship between arrhythmia incidence and coronary lesion location remain limited and are essential for improving risk stratification, monitoring, and therapeutic strategies. Objective: To evaluate the burden of arrhythmia incidence in ACS patients and examine its correlation with coronary vessel involvement at Dr. Ramelan Naval Hospital, Surabaya. Methods: A prospective clinical study was conducted on 150 ACS patients treated between January and July 2024. Patients were categorized according to diagnosis (NSTEMI or STEMI), gender, age group (
