Thanks for your question on Health Care Magic.
I can understand your concern.
By your history and description, possibility of
heart block is more in your friend's case.
It is conduction defect in heart when impulses are regularly conducted.
So heart is not beating properly and hence blood circulation in the body is also not proper.
Pace maker insertion is must for him.
If he is not willing for pace maker, he may develop
brain damage (
paralysis) due to decreased blood supply to brain.
Sudden stoppage of heart is also seen due to heart block. So sudden
cardiac arrest may occur and it is life threatening.
So convince him for pace maker insertion.
Hope I have solved your query. I will be happy to help you further. Wishing good health to your friend. Thanks.
