question: im a 50 year old female,167lbs 5 8 . I ve had heart palipatations since around 17 yrs old. Up until the last 6 months I only had them on and off. When I would eat chocolate or drink caffine. Only when I was pregnant when I was 25 did I have them for 24 hours straight. Recently I get them right after I eat anything. Do anything even just a little physical,like walking or doing nothing at all. Everyday I have them for at least 1-3 hours combined. It is not anxiety. My dad had palpatations all his life. Started with angina at about 46 yrs.
