New quantitative methods for evaluation of dynamic changes in QT interval on 24 hour Holter ECG recordings: QT interval in idiopathic ventricular fibrillation and long QT syndrome.
OBJECTIVES To introduce a nomogram of the normal QT interval at various heart rates measured from 24 hour Holter ECG recordings in healthy subjects with respect to age and sex and to use the nomogram to characterise dynamic changes in QT interval in patients with idiopathic ventricular fibrillation (IVF) and the long QT syndrome (LQT). METHODS The study group consisted of 422 subjects: 249 he...
متن کاملA 24-hour Ambulatory Ecg Monitoring in Assessment of Qt Interval Duration and Dispersion in Rowers with Physiological Myocardial Hypertrophy
UNLABELLED Myocardial hypertrophy (MH) due to cardiac pathology is characterized by an increase in QT interval duration and dispersion, while the findings for exercise-induced myocardial hypertrophy are contradictory. The majority of published research findings have not explored this relationship, but there have only been a few conducted studies using 24-hour ECG monitoring. The aim of the stud...
متن کاملTwelve hour reproducibility of choroidal blood flow parameters in healthy subjects.
AIMS/BACKGROUND To investigate the reproducibility and potential diurnal variation of choroidal blood flow parameters in healthy subjects over a period of 12 hours. METHODS The choroidal blood flow parameters of 16 healthy non-smoking subjects were measured at five time points during the day (8:00, 11:00, 14:00, 17:00, and 20:00). Outcome parameters were pulsatile ocular blood flow as assesse...
متن کاملAmbulatory arterial stiffness index derived from 24-hour ambulatory blood pressure monitoring.
We hypothesized that 1 minus the slope of diastolic on systolic pressure during 24-hour ambulatory monitoring (ambulatory arterial stiffness index [AASI]) might reflect arterial stiffness. We compared AASI with established measures of arterial stiffness and studied its distribution in Chinese and European populations. We used 90207 SpaceLabs monitors and the SphygmoCor device to measure AASI, c...
متن کاملClinical pearls in interpreting 24-hour ECG.
Interpreting a 24-hour ambulatory electrocardiogram (AECG) is important for the evaluation of patients with suspected arrhythmic events. Clinical pearls in interpreting the 24-hr ECG are presented in this article.
