To start, my main qualifications is recognizing and treating life-threatening conditions, so really only your dr is qualified for a real answer. You can DM me if you feel uncomfortable, but what is your major medical history? Medications? How long has it been going on? Does your HR feel irregular? Do you have dizziness, chest pain, nausea, SOB, or pain anywhere else? Have you passed out recently? What is your height and weight? And most importantly, what did the medical professionals say about it in the past about it? Without any other info tho i would recommend seeing your primary dr about it, although it sounds like you already have from your response so far.
