• Rare case highlights life-support technology sustaining vital functions in critical collapse • Unusual recovery following severe cardiac failure caused by acute heart muscle inflammation

A rare medical case was recorded in eastern China, where a man recovered after his heart completely stopped for more than 40 hours in what doctors described as an extraordinary event in modern medicine.

A man in his forties was taken to hospital after experiencing severe chest tightness and breathing difficulties, before suffering a sudden cardiac and respiratory arrest. Repeated resuscitation attempts failed to restore his heartbeat.

Medical staff at a hospital affiliated with Zhejiang University used extracorporeal membrane oxygenation (ECMO), a life-support system that temporarily replaces heart and lung function by circulating oxygenated blood through the body, alongside an additional device to improve circulation and reduce cardiac strain.

For around two days, the patient remained without a meaningful pulse while doctors continued intensive resuscitation efforts using advanced life-support equipment.

After more than 40 hours, heart function gradually improved before normal rhythm returned, allowing doctors to withdraw support devices once the patient stabilised.

According to medical reports, he was discharged about three weeks later fully conscious and without significant neurological complications.

Tests revealed the cause was acute and rare inflammation of the heart muscle, a condition that can rapidly lead to sudden cardiac failure.

Doctors note that survival after prolonged cardiac arrest with near-complete recovery is extremely rare in emergency medicine and reflects the growing capabilities of modern life-support technology.
