After the heart stops how long will the brain continue to work?

After the heart stops how long will the brain continue to work?

Cardiac arrest: There are no hard and fast rules and if the body is significantly cooled the brain can last longer than we used to think it could. This is why we're beginning to chill cardiac arrest patients when appropriate. In general after a couple of minutes of no blood flow nothing is likely to be coming back. After a minute, maybe...... ...Read more

I've been having fatigue, left arm pain and foggy brain to the point where I have a hard time putting a sentence together. Can this be some sort of heart problem?

Yes, but...: If you're 24, it's very unlikely for this to be a heart attack or stroke. If you were 60, and this just started 10 minutes ago, i'd be very worried and would recommend the er immediately via ambulance (911).

Random episodes of dizziness & lightheadedness/fainting with brain fog. BP & heart rate normal. CT scan & all blood work normal. What can it be?

Dizzyness: What a waste of money and resources doing all those tests on a 19 year old with history of anxiety, especially if liver disease is under control. If its positional, you have BPPV O/W vestibulitis, but there is no fainting. You have "panic attacks". I know most doctors practice defensive medicine especially in ER. ...Read more
