Love to hear everyone's perspectives. In ways, yes , it ***** to be us but I love that we re not alone. I too am most symptomatic in the morning, after a decent meal, after standing or walking very little and yes.. Before the period. Recently pinpointed top 3 triggers are rainstorms( or a cool front that involves barometric pressure drops), dehydration and the week before my period. My cardiologist is fighting to help me get through these without crashing which for me means a day or 2 in bed with severe fatigue, low BP that Midodrine can sometimes help and the inevitable Crawling to bathroom or eat and passing out in between. Also yes I have noticed that my hr is always lower when I am feeling worse. On good days heart rate range is 90's to 120's . On poor days its in the low 70's and maybe hits 100 if I move too quickly. I find that strange too.
