Abstract

Although the impact of age and gender on QT and QTc intervals on conventional electrocardiogram (ECG) has been well studied, the impact of these factors on mean QT and QTc intervals measured with ambulatory ECG monitoring has not been studied. The aim of this study was to assess the impact of age and gender on mean QT and QTc intervals measured with ambulatory ECG monitoring. Recordings of ambulatory ECG monitoring from 380 patients without significant cardiac abnormalities were analysed. The mean QT interval was longer in women (390.5 [373.0-405.0] ms) than in men (380.0 [366.0-397.5] ms) (p
