I have not heard of this before, can it be seen on the NHS website ? If it's correct then it's a real slap in the face and lets just rename it Londonstan
I might have got the 5 year rule NHS confused with paying taxes over the previous 5 years if you return to the UK within 5 years. The tax situation is, as per usual, very complicated. But I recall reading about having to prove you really have returned permanently to the UK (parts of the rules may be different for Wales, Scotland, Northern Ireland) and this link informs about that: https://www.gov.uk/guidance/using-the-nhs-when-you-return-to-live-in-the-uk So a citizen cannot return for a short visit just to avail of the NHS and then go away again ..... they seek proof of permanence in "the ordinary residence test" (although I think that could be done via a short-term rental and then reversed after having treatment!). They treat expats as aliens when they return. Better to go back by inflatable boat.
Your doctor seeing the arrhythmia on your ECG would explain them prescribing a pacemaker. Your doctor would need to know if a single chamber or dual chamber type is best for your arrhythmia and your echo seems like the most obvious ways to determine what type. Your blood work was normal which makes statins precautionary to a heart attack I suppose . Elevated cholesterol, particularly LDL, would have explained the statins. Would lowering cholesterol with statins reduce stress on the heart and lessen the need for a pacemaker? I do get mild muscle cramps from Atorvastatin but for the past two years I no longer have spells where I felt too tired to do anything. Unfortunately my Tinnitus also got better and is no longer blocking out the neighbors.
