sure I have a lot of stress in my life, as many of us do, I have been experiencing rapid heat beat, even when resting. Sometimes I feel pressure in my chest as my heart feels like if going to jump out of my chest! I have consulted with my physician, and am currently wearing a heart halter for 48 hrs, next step is a stress test. My concern is or could this be related to stress? I am currently 52 yrs old employed female at 5'3" 125 pounds. active life style... I just ran upstairs and my heart is racing/ and felt weak ?
