【摘要】：目的:對(duì)兒童早復(fù)極波心電圖的危險(xiǎn)分層指標(biāo)進(jìn)行初步分析,提高對(duì)兒童早復(fù)極波心血管預(yù)后的認(rèn)識(shí)。方法:收集早復(fù)極波兒童128例,分析早復(fù)極波分布導(dǎo)聯(lián)、J波形態(tài)、J波振幅、J波后ST段形態(tài)、J波時(shí)限、J波與R波振幅的比值(J/R比值)、Ⅱ、V5導(dǎo)聯(lián)的T波與R波振幅的比值(T/R比值)等心電圖危險(xiǎn)分層指標(biāo),并按性別分組,進(jìn)行比較分析。結(jié)果:早復(fù)極波兒童男70例,女58例;年齡3個(gè)月~14歲6個(gè)月,平均(5.3±3.5)歲。早復(fù)極波分布于下壁導(dǎo)聯(lián)47例(36.7%),側(cè)壁導(dǎo)聯(lián)51例(39.8%),廣泛分布者30例(23.4%)。J波振幅0.2mV 104例(81.2%),≥0.2mV 24例(18.8%)。J波為頓挫型76例(59.4%),切跡型52例(40.6%)。J波后ST段呈上斜型102例(79.7%),水平或下斜型26例(20.3%)。J/R比值(14.7±11.3)%。Ⅱ、V5導(dǎo)聯(lián)的T/R比值為(34.5±15.3)%。J波時(shí)限60ms 2例。以上指標(biāo)按性別分組進(jìn)行比較,均無(wú)顯著性差異。結(jié)論:兒童早復(fù)極波下壁導(dǎo)聯(lián)及側(cè)壁導(dǎo)聯(lián)分布率相近,廣泛分布者少見(jiàn)。J波振幅多0.2mV,多為頓挫型,J波后ST段多呈上升型,J波時(shí)限絕大多數(shù)60ms。男女早復(fù)極波特征相似。兒童早復(fù)極波多為良性心電圖變異,但其遠(yuǎn)期心血管預(yù)后尚不明確。
[Abstract]:Objective: to analyze the risk stratification indexes of early repolarization electrocardiogram (ECG) in children and to improve the understanding of cardiovascular prognosis of early repolarization wave in children. Methods: 128 cases of children with early repolarization wave were collected. The risk stratification indexes of ECG, such as the ratio of J / R amplitude and T / R ratio of T wave to R wave amplitude and T / R ratio of St segment / J wave / R wave after St segment / J wave and T / R ratio, respectively, were analyzed in the early repolarization wave distribution lead / J wave pattern / J wave amplitude and T / R ratio of St segment shape / J wave and R wave, respectively, and the ratio of T wave to R wave amplitude in lead 鈪，
