Hi all - my cardio doc is sure that there is nothing wrong with my heart but says that if I'm still having palpitations and am worried, we can discuss my having a small monitor inserted under the skin, which will stay there for up to 2 years.  I admit, I do still get worried during the bad runs (not having much trouble at moment, touch wood!) - does anyone know anything about this type of monitoring please?  Thanks for any advice anyone can give
