The girl had a normal QT interval (QTc=0.37) on the resting electrocardiogram (ECG). Infusion of induced QT prolongation (QTc=0.62) and frequent occurrence of multiform . Her Holter ECG showed a prolongation of the QTc interval with a shortening of the RR interval. Low-frequency power (LF...

BACKGROUND: Physiological changes in the QT interval caused by sleep are important in the evaluation of the normal QT interval. Traditionally, Bazett's formula is used for correcting the QT interval for heart rate in childhood. We set out to establish the QT-RR relationship in infants during ...
Common side effects of passion flower include confusion, altered consciousness, impaired coordination/balance/speech (ataxia), dizziness, drowsiness, liver toxicity, blood vessel inflammation (vasculitis), nausea, vomiting, pancreas toxicity, heart rhythm disturbance (prolonged QT interval), and rapid ...
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, ...
