How person feel when experience a heart attack?

It varies with the person. Personally, the first thing I noticed was my left arm aching. The ache you feel when you get extremely cold. Nothing in the chest. Thought it was just a muscle ache. 10 minutes later, I started sweating and had a slight tremor in my whole body. Figured what it was, drove to the hospital, walked in and when they asked what I wanted, I calmly told them Oh I'm having a heart attack. No point in getting excited about it. Some people feel very little and some say an elephant is sitting on their chest.
