目的 探讨不同群体心电图Q-Tp间期(QRS波起点至T波顶点)的参考值范围.方法 选取2019年1月-2020年1月粤北人民医院体检中心的正常体检者378例,使用同步12导联心电图对其Q-Tp间期进行观察,并使用Bazzett公式校正.根据年龄分层将所有研究对象分为3个年龄组,18～35岁为青年组,36～60岁为中年组,61～70岁为老年组,并根据性别不同再将每个组分为男性亚组和女性亚组.对比不同组间患者Q-Tp间期和校正Q-Tp间期的差异情况.结果 经单因素方差分析,不同年龄组患者,其Q-Td、Q-Tcd、Q-Tpd和Q-Tpcd值比较差异均无统计学意义(P＞0.05).不同性别亚组中,女性体检者的Q-Tcd和Q-Tpcd水平均高于男性体检者,差异均有统计学意义(P＜0.05).结论 不同年龄分层的健康体检者,其个体间Q-Tp间期和校正Q-Tp间期无明显差异,但不同性别个体间Q-Tp间期和校正Q-Tp间期有差异,女性Q-Tp间期和校正Q-Tp间期水平高于男性.
