The slope of the QT/RR relationship for the patient was below the lower limit of the normal range. This report describes the unusual relationship of QT interval to RR interval and heart rate variability in a long QT syndrome patient with a normal QT interval on resting ECG. 展开 ...

Daytime mean HR gave a mean value of 93 ± 10 (range 71148), while during night hours it was 74 ± 11 (range 5498). The minimum QT interval averaged 261 ± 10 ms for HR> 120 and the maximum 389 ± 9 ms for HR ¤ 60; the corresponding mean value of QTc (i.e., QT corrected...
QTc values for each formula were plotted against age and RR interval. Analysis of variance and regression analysis were used to compare the four formulae and the QT-RR relationship. RESULTS: Mean age was 17.7 weeks (range 4-72) and mean weight 6.3 kg (range 2.68-12.7). The QT-RR ...

Beat-to-beat variability of the QT interval (QTV) is sought to provide an indirect noninvasive measure of sympathetic nerve activity, but a formal quantification of this relationship has not been provided. In this study we used power contribution analysis to study the relationship between QTV and...
Various QT interval variables and heart rate variability parameters were studied in six patients with ventricular fibrillation but without heart disease and compared with findings in 21 normal persons. QT and QT dispersion (QTd) were measured from conventional 12 lead ECGs: for dynamic QT analysis, ...
