Hi @daxrrr. Glad to see you come aboard. I have been treated for several years for atrial fibrillation and irregular heart beats; perhaps my experience can be of some help to you in comprehending your palpitations. Like you, I got anxious when I got my diagnosis four years ago, but that soon went away and my only reminder has been on the EKG performed with my annual physical examination.
Which makes a point for me: Would you consider taking up your problem with your primary care doctor in the context of a regular annual physical? As a general rule, these preventive exams are covered by health insurance with little or no copayment required. Moreover, the customary set of routine rests might disclose the "something else" that you suspect. I have done some research in this area recently and found that heart palpitations usually resolve themselves within a few days or weeks. Also palpitations can be caused by stimulants, Vitamin D deficiency, unbalanced electrolytes (especially magnesium or calcium), dehydration, and lack of exercise (in addition to drugs and anxiety).
Have your doctors said why the palpitations are so obvious to you? Having suggested anxiety, did they mention it might cause surging adrenalin that would promote palpitations? Did they mention anything about common medications that might help?.
Before you see the doctor, would you consider studying the problem by Googling "how to stop heart palpitations due to anxiety" and scrolling down to "People also ask" and checking each of the questions that follows — and all the questions that open up as you go down the list? If I can help with any of this, just say so and I'll get right on it. Martin
