So I think that MAYBE I have this figured out. When determining risk for QT prolongation, you would look at the QTc value, rather than the QT value. My numbers were 484/418. Risk for females is above 450. Since my QTc is 418, I'm probably o.k. Because I have "marked sinus bradycardia" that would probably account for the very high QT value. I assume the very slow heart rate is due to excessive training throughout highschool/college as a long-distance runner/marathoner. This could also explain the occassional dizziness/fainting episodes I've experience in the past. Hmmm. . .wish I'd have known about this sooner.
Did I get this right, Trey? Or is the 484 a concern?
