Ischaemic Supraventricular Tachycardia: A Rare Case Report

Abstract

The incidence of supraventricular arrhythmias other than Atrial Fibrillation (AF) and atrial flutter in postmyocardial Infarction (MI) patients is usually rare. The incidence of in-hospital AF after MI ranges from 5%-18%. Paroxysmal Supraventricular Tachycardia (PSVT) occurs in less than 10% of patients after an acute MI. Herein, the authors presented a case of a 47-year-old male presented to the Casualty Department with chief complaints of palpitations for the past six hours. The Electrocardiogram (ECG) revealed Supraventricular Tachycardia (SVT), and immediate pharmacological cardioversion was performed. Coronary Angiogram (CAG) was conducted, which revealed double vessel disease with critical lesions in the proximal Right Coronary Artery (RCA) and mid Left Circumflex (LCX). Percutaneous coronary intervention was performed for both lesions. The patient was discharged in a stable condition. Prompt and immediate diagnosis of arrhythmias is crucial, especially in patients with MI, to reduce mortality and morbidity.
