Key result
A new physiological method for heart rate correction of the QT interval using linear regression from exercise data successfully removed heart rate dependence and maintained biological differences.
Why the study?
Does a new physiological method for QT interval rate correction remove the dependence of the corrected QT interval on heart rate in subjects with varying autonomic states?
Population
Subjects expected to have different QT intervals and different QT interval-heart rate relations

Should not yet alter practice; leaves open prospective validation of exercise-derived QT correction.

Does a new physiological method for QT interval rate correction remove the dependence of the corrected QT interval on heart rate in subjects with varying autonomic states?
A novel physiological method for QT interval rate correction using exercise test data effectively removes heart rate dependence while preserving biological differences among patients.
Patrick Davey (1999) conducted an observational in QT interval rate correction. Physiological method for heart rate correction of the QT interval (QT 60 and QT y intercept) was evaluated on Dependence of the corrected QT interval on heart rate and maintenance of biological differences. A new physiological method for heart rate correction of the QT interval using linear regression from exercise data successfully removed heart rate dependence and maintained biological differences.
