A heart attack is caused by a prolonged reduction in blood/oxygen supply to the heart as a result of a blockage in one of the vessels which supplies the heart. Tissue/cell death then occurs as a result of this and the area is said to be infarcted. A cardiac arrest simply means that the heart has stopped pumping blood around the body due to a disturbance in heart rhythm,- most commonly ventricular fibrillation. Many different things can cause this. A heart attack itself can lead to a cardiac arrest if blood supply is not restored to the heart quick enough and/or blood supply is completely blocked off. Unconfirmed reports are suggesting MJ died of an overdose of prescription drugs which can cause both respiratory and cardiac arrest. You can have a heart attack without experiencing the changes in rhythms that can lead to a cardiac arrest. For example, blood supply may only be partially cut off. If you have a cardiac arrest, you lose consciousness almost instantly.

4 weeks ago during a minor heart operation to try to repair a slow heart beat I went into cardiac arrest. I was clinically dead for 25 minutes and 9 attempts were made with the electric paddles to try to resuscitate me. I was put into an induced coma for a few days in ICU and in hospital for 2 weeks but now 4 weeks later I am still in a lot of pain and find it difficult to sleep. Any movement give me bad chest and back pains. Is this normal ????

I walked upstairs and was slightly out of breath. I sat down and noticed my heart rate was elevated but no pain or discomfort. I then noticed I could see my heart rate in my eyes as it caused them to pulse. I'm just wondering if that is a problem.
