Hang on a minute, if you're using up to 24 mg of adenosine, but failing, in
70% of your "SVT" patients, then I suggest that you're trying to convert
something other than SVT! If the patients are "flatlining" then it can't be
a ventricular rhythm, but it could be A-flutter or A-fib. A-flutter is very
similar to SVT on ECG, and fast A-fib will appear "regular" on ECG as it's
so difficult to detect minor degrees of irregularity in rates faster than
160-180 bpm.
