...a racing heart and shortness of breath can also be a sign of an anxiety attack, and a feeling of anxiety is also an indicator of a heart attack.


Di, go to a doctor and get this checked. My husband was at the cardiologist today, and he said that Hubby has a constant and extreme irreg. heartbeat. He will be on a 24 hr. EKG. I don't think the computer is the cause of your heart racing. It is what you are doing at the computer. Sometimes when you settle down and relax, that's when the heart starts up too. Not a good sign.

Call the doctor Di.
