Abstract

From a population-based epidemiologic cohort of children and adolescents who sought medical attention for syncope (n = 151), screening 12-lead electrocardiograms were obtained from 118 patients (79 female) to determine the frequency of significant QT prolongation. The distribution of heart rate corrected QT intervals (QTc) was compared with age- and sex-matched controls. Only one patient had QTc >470 ms.

摘要

在一个以社区为基础的、因晕厥就医的儿童和青少年流行病学队列（n = 151）中，从118例患者（79例女性）中获取了筛查性12导联心电图，以确定显著QT间期延长的发生率。将心率校正QT间期（QTc）的分布与年龄和性别匹配的对照组进行比较。只有1例患者的QTc>470毫秒。
