Abstract In this case report, we describe a patient who presented with chronic symptoms and signs of uremia and persistent accelerated idioventricular rhythm (AIVR) on electrocardiogram. Findings from blood tests, echocardiography, renal ultrasound, and renal scan were suggestive of heart failure with reduced ejection fraction and chronic kidney disease, and attendance of daily hemodialysis sessions led to the restoration of sinus rhythm. Typically, AIVR has a favorable prognosis and, if necessary, medical intervention focuses on addressing the underlying responsible causes. Accumulation of uremic toxins has the potential to trigger the formation of AIVR and clearance of small solutes through conventional hemodialysis may contribute to sinus rhythm restoration.

This is a case of a 59-year-old man presenting with myopericarditis. Over a 2-week period, he developed progressive symptoms and worsening pericardial effusion, leading to cardiac tamponade. Pericardiocentesis revealed hemopericardium, and multidetector computed tomography angiography showed left ventricular free wall rupture. The patient collapsed abruptly, and autopsy confirmed the findings.
