I'll prolong the discussion for one more post. With regard to SPECIFICTY, CAMH's MTWA is near perfect, with 97-99% negative predictive value. That's exactly what one wants with a screening test, good old fashioned rule out power.
With all due respect, urche, the EP community doesn't like the fact that this noninvasive, highly specific, and inexpensive test will lose them invasive EP study business.
Are you an EP?
