Tom: My point is clarified here and in the other posts.  SVT is a largely non-specific term (vs VT) for rhythms with a rate at or above 150, when, really, Sinus Tach should be in that terminology based upon strict nomenclature.  We have given up attempting to identify the true rhythm and its implications, based solely upon a rate (generalizing those who do such things).

 

My question was of the seemingly randomness of "150 bpm" to justify ceasing to interpret and be content with a non-defined (non-existing) rhythm.  No need to worry--when my crews use the term "SVT", I pounce  :)   Same with PEA...
