I have two bad heart valves discovered about 18 months ago after a bout of COVVID that I am being monitored for. Believe me, I have had a lot of testing and my arteries are "clean." I have had ECHOS, a stress ECHO, a cardiac MRI, a PET SCAN to look at my arteries, two TEE's, lots of blood work etc. I am 69 years old, eat only fish and lots of veggies and have done so for years. About 3 months ago I started having lots of heart palpations (every 5 to 10 m minutes round the clock). My cardiologist had me wear a heart monitor for two weeks and the results show I am not in AFIB which is the important thing. My rhythm is mostly normal sinus rhythm. My cardiologist is at Cedar's Sinai so I know I am getting the best of care and advice. I was told the next step will be to place me on a beta blocker which will cut down the adrenalin that is probably causing my palpations which are VERY concerning to me. I do not have high blood pressure, and in fact, my blood pressure tends to be on the low side. I am worried about taking a beta blocker and the possible side effects but am willing to try it to see if it will help. Your cardiologist needs to have you wear a heart monitor (they have several advanced ones that are much better than the old Holter Monitors) to find out more about your palpations.
