Synchronized Cardioversion Performed During Cold Water Immersion of a Heatstroke Patient.

Area of Science:

• Emergency Medicine
• Cardiology
• Environmental Medicine

Background:

• Heatstroke management can involve therapeutic hypothermia using cold water immersion.
• Patients with severe heatstroke may develop life-threatening cardiac arrhythmias.
• Unstable ventricular tachycardia requires prompt electrical cardioversion.

Observation:

• A patient with heatstroke developed unstable ventricular tachycardia during cold water immersion therapy.
• Synchronized cardioversion was administered while the patient remained in the immersion body bag.
• The procedure was performed without removing the patient from the water.

Findings:

• The electrical cardioversion was successful in restoring a stable heart rhythm.
• The patient survived the event and was discharged neurologically intact.
• No adverse effects were observed for the patient, staff, or equipment.

Implications:

• This case demonstrates the feasibility of performing electrical cardioversion during cold water immersion.
• It suggests that immediate treatment of critical arrhythmias can be achieved even in challenging environmental conditions.
• This approach may be considered in similar clinical scenarios involving patients requiring both hypothermia and cardioversion.
