简介:目的分析心肌致密化不全(noncompactionofventricularmyocardium,NVM)儿童T波峰末间期(Tp-Te)、校正的Tp-Te间期(Tp-Tec)、Tp-Te与QT间期的比值(Tp-Te/QT)等心肌复极指标的变化及其临床意义。方法收集34例住院NVM患儿作为NVM组,随机选取健康儿童34例作为对照组,比较两组12导联体表心电图心率、校正的QT间期(QTc)、Tp-Te、Tp-Tec及Tp-Te/QT等指标。结果34例NVM患儿中5例(14.7%)并发室性心律失常(室性早搏4例,室性心动过速1例)。NVM组心率较对照组明显加快,差异有统计学意义[(128.8±21.8)次/minvs.(113.1±17.5)次/min,P〈0.05]。两组QTc、Tp-Te比较,差异均无统计学意义[(404.8±30.9)msvs.(402.6±21.4)ms,(76.1±17.3)msvs.(72.1±13.9)ms,P均〉0.05]。NVM组与对照组比较,Tp-Tec明显延长,Tp-Te/QT明显升高,差异均有统计学意义[(112.7±26.8)msvs.(98.6±16.6)ms,(0.27±0.06)vs.(0.23±0.04),P均〈0.05]。结论儿童NVM存在跨室壁复极离散度的异常,易导致室性心律失常的发生。由于心率等因素的影响,Tp-Tec、Tp-Te/QT对儿童NVM发生室性心律失常的预测价值高于Tp-Te。

简介:摘要目的本研究探讨急性脑外伤患者心电图相关指标的变化及其与预后的关系。方法前瞻性收集2014年1月至2018年1月就诊的急诊脑外伤患者289例,最终入选219例及与相匹配的对照组220例,入院1 h及住院72 h行心电图,测算P波离散度(Pd)、校正后QT (QTc)、校正后QT离散度(QTcd )、校正后Tp-e间期(Tp-ec )、校正后Tp-e间期离散度(Tp-ecd )及Tp-e/QT比值,分别应用独立样本t检验和配对样本t检验比较脑外伤组第1天和对照组、第1天和第3天上述指标的变化,分析外伤组心电图指标与病情轻重及住院期间不良事件(MACE)的关系。结果脑外伤组患者第3天QTc、Tp-ec和Tp-e/QT较对照组及第1天均增加,差异有统计学意义(P均<0.05);格拉斯哥(GCS)评分中重度脑损伤患者Tp-ec、Tp-e/QT较评分为轻度者增大,差异有统计学意义[(150.48±16.58 )vs(130.14±11.86 ),P=0.006 ;(0.29±0.04)vs (0.23±0.03 ),P=0.030]。住院期间出现MACE组患者Tp-ec、Tp-e/QT较无MACE组增大[(149.76±12.52 )vs(128.84±12.47 ),P <0.001 ;(0.30±0.04 )vs (0.21±0.03),P <0.001]。结论急性脑外伤患者Tp-e和Tp-e/QT与病情严重程度相关,一定条件下可作为短期预后的评价和预测指标。
