It could be PVCs. I recommend going to a doctor that is knowledgeable and will likely have you wear a heart monitor that will read your heart beat over a certain period of time and record the information for your doctor to look at. Caffeine and some other things can irritate PVCs too. Also, finger heart rate/oxygen monitors are available at the store or online, and you can get a journal or paper and write down when you feel these skipped beats, see if your heart rate is normal, and make a note of your activity and the date and time. This will be very helpful to track for you and for your doctor.
I think I just commented on your question similar to this somewhere else, but no, you are not alone in this. I have an otherwise healthy and normal heart, but I will get skipped beats (PVCs in my case) with my anxiety, with stress, hormonal changes and sometimes just a few out of nowhere. I've had them for 12 years (as far as I know) and I learned to live with them for a while. Let me assure you of this, when you focus on them and get anxious over them, they will intensify. No doubt about it. It's a hard cycle to break but you will.
Thx I had a echo done 2 years ago and it came back good
It's always hard when we have become anxious about something to really get a good picture of it. You are hyper focused on your heart beat-- there is a really good chance it is not doing what you think it is doing. Some people have palpitations and anxiety can cause this. Because we can't really get a full picture just from a verbal description here and you have ongoing anxiety which means you may be overanalyzing normal things--- the really best thing to do is to have a well check physical and tell the doctor about this. They can provide further testing to rule out any heart issues--- and then once that is done, you can begin working on your anxiety. In the mean time, what about a go to activity when you get hyper focused? Like taking out a book and reading, turning on the radio, etc.--- something you do to change your thought process and actions at that moment to get you thinking about something else. good luck
