Key result
Sudden vagal-induced RR increases prompt dynamic changes in the uncorrected QT interval.
Why the study?
Few articles have addressed the dynamic response of the uncorrected QT interval to sudden vagal-induced increases in RR interval in subjects without structural heart disease.

No quantitative QT-RR data reported precludes clinical application; leaves open need for prospective autonomic studies.
Castellanos et al. (2000) studied No demonstrable structural heart disease. Sudden vagal-induced increases in the RR interval was evaluated on Dynamic response of the uncorrected QT interval. The dynamic response of the uncorrected QT interval to sudden vagal-induced increases in the RR interval is discussed, but no quantitative results are reported in the abstract.
