A 23-year-old woman with fulminant myocarditis was rescued at a hospital in Xi'an, Northwest China's Shaanxi Province, according to Pear Video on Sunday. 

The patient, whose heart had stopped beating for three days, was treated immediately with ECMO to provide breathing and heart support, and eventually resumed normal heart functions after teetering on death. 

"The patient always stayed up late at night, which greatly weakened her body's immune system. She caught a cold a few days ago, triggering myocarditis which directly led to cardiogenic shock," said a doctor at the hospital in the video. 

Thanks to the timely ECMO treatment, the patient was able to remain conscious and talk with people around her even without a heartbeat. The young woman was surprisingly upbeat, and sent messages to her friends via Wechat, telling of her miraculous experience. 

The video, posted on Weibo at midnight, soon attracted widespread public attention and stirred up health concerns among young people, gaining 20,000 comments and reposts.

"Dilemma: me, staying up late reading this post, versus the post, telling us severe consequences of staying up late," read one comment.

Another netizen gained 30,000 likes after making fun of himself: "When I saw the video, I promised myself to never to stay up late again, ever. But the next day, everything went back to normal and I broke my promises."
