What heart rate indicates a heart attacks is coming?

Heart attack : So, this is your second question about this same concern. You need to speak to a primary care doctor about your concerns. There is no particular heart rate that is associated with a heart attack. There are EKG changes and blood test changes. I am saying this because I care, you may have anxiety

Agree with Dr. R: It is not feasible to provide a meaningful opinion without taking additional history, physical examination and may be some tests. It would be prudent to see your doctor and discuss if you may be depressed. Counter-intuitive as it may seem, exercise may help. Start with low intensity exercise such as walking and gradually increase the intensity as tolerated. Drink more water. Wish you good health!
