supraventricular tachycardia. Well that was a big help. Billvon: thanks for putting it into English, since the respondent must think this is a forum for doctors. LoL. Sorry about that. I just typed that in a hurry because I had to go out. I figured at least if you had that bit of info you could go do a quick search in google. Anyway Billvon gave you a good description. TonyJ I hope everything works out.
