student question on murmurs

Published

If a murmur were charted as II/IV what would that mean? My understanding is that this is a grade 2 to grade 4 murmur; meaning, that the sound ranges from clearly audible, but faint to loud, associated with a thrill palpable on the chest wall.

I'm curious if this is correct, or was this a type-o; meaning, did the instructor actually mean to chart as II/VI?

My text indicates that a grade II murmur should be documented as "II/VI". So, that's why I'm wondering if "II/IV" is a type-o by my instructor.

Any thoughts would be greatly appreciated.

Murmurs are usually graded on a 1-6 out of 6 scale. Yes, that is most likely a typo, or your instructor is in need of some studying. Likely the Typo answere though, I hope!!

Murmurs were graded on a 1-4 scale for years and years in the past.

Now they have gotten more definitive, but it is still not wrong. I still come across it written like that.

Suzanne4, please clarify. I'm still thinking it's a type-o. The scale we are using is based on a six point scale, not a four point scale, with grade 6 being the loudest with a thrill. Thus, since we are grading murmurs based on this 6 "point" scale, I would think that II/IV is a type-o. Your thoughts are appreciated.
