Hi ,
I am a 22 year old female,
recently ( 6 month ago ) I got palpitations , syncope and pre-syncope,
echo was normal , and on 24 h holter, I had sinus tachycardia but with 190 beats/min !
I am now on isoptine(verapamil) 40 mg twice daily , but still get palpitations sometimes,
what could be the problem , and what should I do ??
Thank you very much ,
