Corrected QT Interval

[Guest]

I'm trying to calculate the corrected QT interval in a query, but I'm not
getting correct #s.
This is what I'm using;

QTc = [fldQT]/Sqr([fldRR])

The formula for Qtc = QT divided by the Square root of RR.

Any ideas what's wrong.

Thanks

What's the context: a form, a query, or what? What values are you
using? What results are you getting? What results do you expect?
