【摘要】：目的:研究左室假腱索(LVFT)者早复极波发生率,并对比分析三型早复极波在LVFT者与正常对照组的发生率。方法:收集2016年5月-11月于宁夏人民医院心脏彩超室行心脏彩超检查者共57 6人,年龄1 8-40岁(平均年龄30.75±5.803),其中心脏彩超提示有左室假腱索者276人,无左室假腱索者300人做为对照组。全部入选者做心电图检查并收集一般资料,性别、年龄,症状,有无心律失常病史。确定早复极心电图,测量心率、P波时限,PR间期、QTc、QRS时限等相关指标,分析左室假腱索组及对照组早复极波的发生率,分析三型早复极波在左室假腱索组及对照组中分布情况。结果:(1)收集心脏彩超提示有左室假腱索者共276人,年龄在18-40岁,男性204人(73.9%),女性72人(26.1%),男性左室假腱索发生率明显高于女性,差异有统计学意义(P0.05),共获得有效心电图276份,其中发生早复极波98人(35.5%),男性80人(81.6%),女性18人(18.4%);无假腱索者共300人,男性205人(68.3%),女性95人(31.7%),获取有效心电图300份,发生早复极波36人(12%)。采用卡方检验,左室假腱索组发生早复极波明显高于正常对照组(P0.05)。(2)左室假腱索组中发生Ⅰ型早复极波8人(2.9%),Ⅱ型早复极波76人(27.5%),Ⅲ型早复极波14(5.1%),对照组组中发生Ⅰ型早复极波6人(2.0%),Ⅱ型早复极波24人(17.4%),Ⅲ型早复极波6人(2.0%),采用卡方检验,Ⅱ型、Ⅲ型早复极波明显高发于左室假腱索组(P0.05,),而Ⅰ型早复极波在左室假腱索组及正常对照组中发生率无差异(P0.05)。(3)对比左室假腱索组及对照组两组人群心电图,PR间期、QT c均无明显差异(P0.05);心率、P波时限、QRS时限均有统计学差异(P0.05),左室假腱索组心率较对照组慢,P波时限及QRS时限左室假腱索组长于对照组。结论:LVFT男性发生率较女性高;本次研究左室假腱索引起早复极波发生率为35.5%;早复极波发生以Ⅱ型居多,发生Ⅲ型早复极波较正常组高;左室假腱索组人群的P波时限、QRS时限均延长。
[Abstract]:Aim: to study the incidence of early repolarization in patients with left ventricular false chordae tendineae (LVFT) and to compare the incidence of type 3 early repolarization in LVFT patients and normal controls. Methods: a total of 57 6 patients, aged 18 to 40 years (mean age 30.75 卤5.803), were examined by echocardiography in the heart color Doppler echocardiography room of Ningxia people's Hospital from May to November 2016, among which 276 patients with left ventricular false tendineous chordae were detected by echocardiography. 300 patients without left ventricular false chordae tendineae were used as control group. All participants were examined by electrocardiogram and collected general data, sex, age, symptoms, any history of arrhythmia. To determine the early repolarization electrocardiogram, to measure the heart rate P wave duration and PR interval QTcP QRS time, to analyze the incidence of early repolarization wave in the left ventricular false tendon chorda group and the control group, and to analyze the distribution of the three type early repolarization wave in the left ventricular pseudoaponeurotic chorda group and the control group. Results there were 276 cases (aged 18-40 years) with left ventricular false chordae tendineae revealed by color Doppler echocardiography, 204 males and 26.1 females. The incidence of left ventricular false chordae tendineae in males was significantly higher than that in females, the difference was statistically significant (P 0.05). 276 effective electrocardiograms were obtained. Among them, 98 had early repolarization wave, 80 men had 81.6 right, 18 women 18 had no false tendon chordae, there were 300 cases without false tendon chordae, 205 male with 68.3%, 95 women with 31.775, 300 valid electrocardiograms, and 36 cases with early reversion. Using chi-square test, The occurrence of early repolarization wave in left ventricular pseudoaponeurotic chorda group was significantly higher than that in normal control group (P0.05. 2) Type I early repolarization wave occurred in 8 patients with left ventricular pseudoaponeurotic chordae tendineae, type 鈪，
