PAROXYSMAL SYMPATHETIC HYPERACTIVITY FOLLOWING CARDIAC ARREST DUE TO MASSIVE PULMONARY EMBOLISM: A CASE REPORT

Abstract

Paroxysmal sympathetic hyperactivity (PSH) manifests with episodes of autonomic dysregulation including hyperthermia, diaphoresis, tachypnea, tachycardia, hypertension, and dystonic posture. Its differential diagnosis is made with several more prevalent pathologies, which can cause a delay in the diagnosis, making knowledge of this disease very important. Herein, we report the case of a patient who was diagnosed with PSH following cardiac arrest and discuss briefly the pathophysiology, clinical presentation, and management of this clinical entity.
