Electrical cardioversion intervention in a patient with heat stroke accompanied by rapid atrial fibrillation: A case report and literature review

This report highlights the feasibility of electrical cardioversion intervention for the treatment of heat stroke complicated by rapid atrial fibrillation. There has never been any mentions in the previous literature of the possibility of electrical cardioversion in the event of heat stroke complicated by rapid arrhythmia. A 61-year-old man with classic heat stroke complicated by rapid atrial fibrillation was admitted to our emergency department. In the early stages of treatment, hemodynamics were not stable under the treatments of aggressive cooling and volume-expanding rehydration. It was considered to be related to rapid atrial fibrillation, and the administration of drug cardiover and control of ventricular rate failed. Subsequently, synchronous electrical cardioversion was given 3 times (biphasic wave, energy: 70J-80J–100J, respectively), successfully cardioversion and hemodynamically stable. Although the patient eventually died of progressive deterioration of multiple organ failure, timely cardioversion might be effective for the treatment of heat stroke complicated by rapid atrial fibrillation.
