I think I am have been misdiagnosed

You story suggests that different docs where adding different meds; instead of one doc controlling all the meds. That said looking at your list you are taking: Jardiance, lisinapril, Lasix Flecainide and metoprolol, aspirin and Plavix. There are interactions between some of these drugs. You are taking anti-arrhythmic drugs and diuretics and anti coagulants, heart failure drug like Jardiance. I would start by talking to my pharmacist and see if anything pops up there. But from just looking at drug interactions you need to make sure you do not get dehydrated for starters. Kidney function and lowering heart rate stick out to me. That said I believe you also should make sure that you tell your story about feeling much worse now that before this began.
What you leave out is what other diagnoses do you have/had besides Afib. Were you legs swollen and did or do you have excess water elsewhere like around your heart of blood vessels? As well as other issues. Did they explain why you needed a watchman? It seems that you describe an increasing amount of time being in Afib. Hence their decision to move to a watchman??

I am sorry to read about your heart issues and all the medications you are on. Remember - knowledge is power. One of the first things YOU should do is go to Web MD Drug Interaction checker. You can put in all of your medications, as well as OTC or vitamin supplements. It will let you know what you should be aware of, especially interactions and whether they are mild, moderate, or severe. This information can be brought to the attention of your primary md or cardiologist. Having knowledge will help you to understand why you are on what you are on. You may also feel more comfortable if any medications are discontinued, even temporarily, as well as what to look for if you need to restart them again. Work with your md or nurse practitioner. It may take some time to get the right combination of medications. Keep a record of your physical symptoms, including any swelling of your legs. Be aware of your mental symptoms, too, as people can get increased anxiety or fatigue, as well. Good luck and feel better.

@pht1123 and @katiekateny pharmacists have interaction checkers and can check interactions of all these meds for you. That might carry more weight with a doctor- coming from another professional. Pharmacists can often better advise on how to stop, whether to taper- better than an MD in my experience.

Pharmacists are wonderful resources of knowledge. Their patient interactions are so important. It is still good to get information for yourself and verify things with your pharmacist. Working together with the health care provider, the pharmacist, and the patient are all essential to have the patient feeling the best they can, with the best outcomes that can be obtained.
