If your ECHO is normal, you never had loss of consciousness
, transient unexplained fall, then in all probability you are not in danger zone. i hope you do not have any of these symptoms.
Moreover your holter and TMT all also normal, which are again reassuring. you are most probably having APC / VPC (premature beats with origin different from normal site of origin). they , when associated with a normal ECHO, are not to be treated if they do not cause bothersome symptoms. Hence you need not worry. if you really have bothersome symptoms because of them you can ask your doctor to increase the dose of metoprolol
, that will help.
So relax and be convinced that there is nothing much. if you still feel there is a problem, consult your cardiologist.
