Hello. I have been experiencing strong heart pounding in my chest for about 2 weeks. It also speeds up, slows down and goes away without warning. Sometimes I feel my blood pressure rise, a few times I went and had it taken. It ranged from 80/50 to 149/99. Of course, the higher one was new to me. I am 46 year old female, I have smoked most of my life, but have slowed down the last few years and since this started, I quit. I was supposed to see my doctor for this in 4 days, however, I had such a scary day I went to the hospital and they have admitted me. My tests start this morning. They are doing an ultrasound, stress, some box thing?? Don't know much more about that one. Secondary, they are checking my thyroid as it, too, can cause this heart pounding?? I don't know. Sounds like it could make sense. Well, I will keep you updated after my tests today. Maybe it will help? Lastly, they are looking at anxiety/stress. Wish me luck!
