背景：超声心动图测量心脏收缩峰值速度(Ts)有助于评估心脏不同步程度。我们根据组织多普勒成像的ts来评估结构正常心脏的室壁不同步程度。方法：对65例健康成人志愿者进行常规超声心动图和组织速度成像检查，测量12个左心室节段中层和基底层的TS、各节段和基底节段的TS延迟及标准差(SD)。测量了6个常用的不同步标记，并对男性和女性进行了比较。数据以中位数(25%和75%)表示。结果：间隔外侧延迟50(20，90)ms，前间隔延迟20(0，55)ms。基底段和所有节段的最长和最短TS之间的延迟分别为100(80,120)和110(83,128)ms。各节段的标准差分别为39(24，52)ms和41(28，51)ms。总体而言，76.9%的病例至少有一个不同步的标志。与男性相比，女性不同步标记物的频率几乎显著更高。最常见的不同步标志是各节段ts的SD(70.8%)，最低的是前间隔-后延迟(21.5%)。结论：通过先前描述的标记物，正常人群几乎具有不同步性，其中许多标记物在女性中更常见。通过其他组织多普勒技术对正常人群进行更多的研究，可能会更好地描述心脏的同步性。(超声心动图2010；27：823-830)
Background: Echocardiographic measurements of time‐to‐peak systolic velocities (Ts) are helpful for assessing the degree of cardiac asynchrony. We assessed the degree of ventricular asynchrony in structurally normal heart according to Ts by tissue Doppler imaging. Methods: We performed conventional echocardiography and tissue velocity imaging for 65 healthy adult volunteers to measure the Ts of 12 left ventricular segments in the mid and basal levels delay of Ts and standard deviation (SD) of Ts in all and basal segments. Six frequently used markers of dyssynchrony were measured and were also compared between men and women. Data are presented as median (25th and 75th percentile). Results: Septal‐lateral and anteroseptal‐posterior delays were 50 (20, 90) and 20 (0, 55) ms. The delay between the longest and the shortest Ts in basal and all segments were 100 (80, 120) and 110 (83, 128) ms, respectively. SD of Ts was 39 (24, 52) ms for basal and 41 (28, 51) ms for all segments. Overall, 76.9% of cases had at least one marker of dyssynchrony. Frequencies of dyssynchrony markers were almost significantly higher in women compared to men. The most frequently observed dyssynchrony marker was SD of Ts of all segments (70.8%) and the lowest was anteroseptal‐posterior delay (21.5%). Conclusions: Normal population almost had dyssynchrony by previously described markers and many of these markers were more frequent in women. Conducting more studies on normal population by other tissue Doppler modalities may give better description of cardiac synchronicity. (Echocardiography 2010;27:823‐830)
