[|Human|] they had her up walking within 15 hours. Her heart stop and they had to revive her she is now in a coma. the doctor said she did not have a stroke, heart A. or blood clots What is going on?, my cousin had a tripple bypass about a week ago. She went through fine.What brought on the coma?
[|AI|]  Hello, If her heart stopped, and she had to be revived then, one of the more likely things that happened resulting now in a comatose state would be BRAIN ANOXIA which refers to a severe lack of oxygen to the brain during the time that the heart was stopped.  Even though there was no heart attack per se according to the doctor something obviously happened to actually bring the heart to a standstill.  There are usually classic radiographic features to brain anoxia after an event like this.  I would focus attention on the PONS region of the brain stem which is where the most likely damage would be done to cause a generalized comatose state. Hope I have answered your query. Let me know if I can assist you further. Take care Chat Doctor.
