查询词典 QRS

By means of signal processing techniques such as the power spectrum function, the auto correlation function and cross correlation function, two kinds of ECG signals when AF does or does not happen were successively analyzed, showing the evident differences between them.

提出了一种简便有效的、由心电图曲线提取QRS -T复合波的新方法，从而获得P波或f波；利用功率谱、自相关、互相关等信号处理技术，对它进行了处理和分析，特别是，比较了未房颤时和发生房颤时的相关信息的显著差别。

Ventricular pacing may cause interventricular asynchrony but its effect on intraventricular asynchrony need further study.

常规右心室心尖起搏致QRS波增宽，可造成心室间收缩不同步，但不一定会造成左心室内收缩不同步。

Though this depends of course upon how one defines things, such as masculinity and femininity.It also depends on the time frame - what may be 100% masculine when something important needs to be done, that is when no significant emotional/egotistical thought should intervene, then 100% masculinity is warranted, but after that thinking and the action, one needs to recede into femininity.The 100% masculinity man need a 100% femininity woman.Only in the traditional sense of masculinity, rather than masculinity as defined by the QRS - but there is no doubt that I, as a misogynist, desire a highly sexually-feminine woman. As a companion, I do not desire either a feminine minded woman or a masculine minded woman.

我的左大腿中间有几个黑色的小痘子，那是我以前写天才哲学时说无间道2海报里的几个明星在装作尸体所得的果报，前几天机缘成熟后我再次看到书里的那张图片，认识到他们并不是在装，而是定在了一个比较高的境界和状态，而且那种状态也根本不是"尸体"，而是代表正义的力量，我以前是把他们误友为敌了，当我认识到这点后，那几个黑痘里的我自己的怨毒当时就感觉到被化解了，几天后，黑痘就慢慢消失了，而这之前在写出那句话到现在的几年里，黑痘一直存在，并成为我自己的吸引地狱黑色灰末的种子。

With deep-wave inversions throughout both limb and precordial leads.

心电图显示正常的QRS波群有一些大幅度的倒波贯穿在心前区和侧段

Methods: QRS score was measured during treadmill exercise testing in 30 patients with CHD and 20 healthy persons.

运动试验是对冠心病诊断及病情判断有价值的无创性手段之一。

According to the theory of wavelet transformation, the singularities of the ECG signal are corresponding to the series of maximum-minimum pairs. The algorithm detects the onsets of Q wave at the scale 3 detail and offsets of T wave at the scale 4 detail. So the duration of QT is calculated by onset of Q wave and offset of T wave.

根据小波变换的原理，心电中的奇异点在变换后将产生一个模极大值和模极小值对，在小波变换3尺度上检测出QRS波群的起点，在小波变换4尺度上检测出T波终点，从而确定QT间期。

The analysis results showed that the strapdown approach will be faced to more error sources with sensor noise and motion disturbance. The simulation results verified this and indicated that the performance of the strapdown approach would not be as efficient as that of the direct approach.3. Analyzing the principle and error model of MEMS QRS gyro for the purpose of practical applications, the paper presented an autoregressive model for the gyro signal by means of time series theory.

应用牛顿力学原理分析了光电稳定跟踪机构的惯量耦合关系和动力学模型，推导了平台单轴伺服回路的控制方程，比较了直接稳定和捷联稳定方案在测量噪声和外部扰动共同作用下的性能特点，仿真结果表明，在同等噪声和扰动条件下，捷联稳定面临更多的误差源，因而最终的稳定精度较难达到直接稳定系统的水平。3。

R waves of the 12 models rose transitorily and abnormally during the occlusion of the left coronary artery; new q waves appeared or original q waves deepened when reperfused for 15 -20 min, further more, the q waves broadened and deepened gradually along with the reperfusion.

QRS波群改变：12只大鼠在结扎左冠状动脉前降支即刻均出现短暂的R波异常增高；再灌注15—20min出现q波或原有q波加深，随再灌注时间延长，q波逐渐加深、加宽。

After QRS detection, the P wave and T wave is detected by the information of the amplitude and slope in certain section. This method works well for normal signals yet it isn't fit for the unmoral signals and diseased signals.

对于P、T波的检测问题，采用在特定区间内通过斜率和幅值加以检测的方法，对正常心电图检测效果较好，但不适用于不规则的和病态心电图。
