We had a woman with recurrant SVT, she got pregnant. In the end she was sorted by administering adenosine. I felt a bit uncomfortable at first as the BNF was singularly unhelpful. Worked and she's we;; so it quite good. Another thing .... has anyone ever seen 3mg work...I never have I usually just start at 6mgs. The most reliable dose seems to be 12mg. What's other folks experience. Iain __________________________________________________ Do You Yahoo!? Get email at your own domain with Yahoo! Mail. http://personal.mail.yahoo.com/
