A 56-year-old patient with a history of coronary artery disease (CAD) and left ventricular ejection fraction (LVEF) of 42% presented with palpitations and easy fatigability over the past 2 days. Initial ECG revealed an irregularly irregular rhythm (1st ECG) indicative of atrial fibrillation (AF). Management included the initiation of amiodarone infusion following the AF protocol, and low molecular weight heparin (LMWH) was administered. Subsequently, the patient reverted back to normal sinus rhythm (2nd ECG). Key considerations in this case include the preference for rhythm control over rate control and the importance of promptly initiating anticoagulation to prevent thromboembolic events.
