Prolonged QTc Interval and Elevated Heart Rate Identify the Type 2 Diabetic Patient at High Risk for Cardiovascular Death. The Bremen Diabetes Study

Abstract

Easily established ECG criteria such as prolonged QTc time and elevated heart rate obviously are powerful predictors of cardiovascular death in type 2 diabetic patients and are possibly superior to the traditional cardiovascular risk factors. As heart rate itself is an independent risk indicator, QTc time should be calculated by a formula (e.g. Fridericia's equation) that more accurately corrects QT for heart rate than the widely used Bazett's formula.
