I have sick sinus syndrome and have had pacemaker since 1999. Is this condition hereditary?
No sick sinus syndrome is not in itself hereditary. Sick sinus is diagnosed when the heart changes rhythm without a known cause and usually the heart puts itself back into a normal sinus rhythm. Sick sinus syndrome is not necessarily harmful. A-fib is a condition of the ventricles where they do not contract but only quiver. The problem with this is that it causes some people to develop blood clots. If you dont want to use metoprolol then you should quickly get a second opinion.
