There are studies about women and menopause, when their estrogen level drops it can lead to heart disease. They do not have conclusive answers as to why yet but it accounts for more women getting it after this time. When I asked my doctor this, I also have 1 ovary and am concerned about this among other things), she looked at me with 2 heads. That is until I pointed out it was studied...I really think however that you have had more than enough tests and now you should try to focus on stress reduction, getting enough sleep, regular exercise, and a plant based diet or one that included omega 3's such as olive oil and the mediterranean diet which also included fish and salmon. It has been proven that women in these areas have a much reduced amount of heart disease due to their diet.
My heart rate seems okay, it's just that it feels irregular all the time. You know, beat, beat, stop, flutter, beat hard, beat hard, beat, beat and son on. Did you ever hear of anything like this?
I can relate. I am having all of the same symptoms you are having and have had all the heart testing that all came back normal. Hormones can do a lot to the body. Try increasing your calcium and make sure that you are getting enough vitamin D. Vitamin B also helps to calm. Stay away from allergy medication if you can, it makes the symptoms a lot worse. Make sure you are drinking enough water and cut back on caffeine. Symptoms of heart disease would be chest pains, lightedness with chest pain, shortness of breath, difficulty climbing stairs or unable to climb without stopping to rest, pressure in chest. Heart racing and heart awareness are not symptoms of heart disease. The heart rate can go up to 190 and the heart is still doing its job. Once it reaches 200 beats per minute, then it is not doing its job. Around 160 usually people are so out of breath that they cannot talk. If you can talk, you are okay.
