I have discussed this before about Palpitations. I had a Dual PM fitted in May 2018 and had problems. The 6 week check up they altered the PM and from then on I had nothing but Palpitations. A week later I went back and they said nothing was wrong with the settings of the PM were correct and, to go and see a Doctor to give me something to change this. I did and he gave me a Beta blocker, it didn't make any difference . I noticed that the worst of the Palpitations seemed to start at 10pm on a Monday night so I noted it down for about 6 weeks and found it crept every 21hrs. I went back again to discuss this, it took a lot of convincing but, eventually they turned the restriction off. Well no palpitations but, now I have chest pains which occur intermitantley,(usually starts about 10am and mainly when I'm sitting down watching TV) As you do I Google it and it could be Anxiety or Panic attacks, before I go back again, any thoughts on this?
