Atrial Standstill: A Rare Cause of Pediatric Stroke and Management Strategies

Abstract

In patients with atrial standstill (AS), a lack of atrial contraction will likely cause blood flow stagnation in the atria. Thromboembolic complications are highly prevalent in such cases. We present a case involving a ten-year-old boy diagnosed with AS after presenting with a cerebral embolism. Subsequently, the patient underwent a successful endovascular thrombectomy and pacemaker implantation. Atrial electrical activity recovered six months following dual-chamber pacemaker implantation. Prompt recognition and management pose challenges in patients with previously undiagnosed AS who present with acute ischemic stroke. Additionally, anticoagulation therapy and monitoring of atrial activity are crucial for preventing thromboembolic events.
