目的：虽然以前研究过年龄对QT间期和QT离散度（QTd）的单独影响，但没有数据表明年龄和其他生理或生活方式因素同时影响健康受试者的QT间期和QTd。我们研究了年龄、性别、体重指数、吸烟状况和血压对这些心电图参数的影响。设计：观察性研究。环境：学术医疗中心。参与者和测量：年龄、性别、体重指数、吸烟状况和血压来自191名连续健康受试者（男性101名，女性90名，年龄范围19-89岁）。研究对象根据年龄分为三组：
Objective: although the isolated effects of age on QT interval and QT dispersion (QTd) have been previously investigated, no data are available on the simultaneous effects of age and other physiological or lifestyle factors on QT interval and QTd in healthy subjects. We studied the effects of age, gender, body mass index, smoking status, and blood pressure on these electrocardiographic parameters.Design: observational study.Setting: academic medical centre.Participants and measurements: age, gender, body mass index, smoking status, and blood pressure were obtained from 191 consecutive healthy subjects (101 males and 90 females, age range 19-89 years). The subjects were divided into three groups according to their age:
