查询词典 amplitude

Methods:We ablated the ventricular tachycardia of 12 patients with normal hearts by the catheter, using pace mapping and activation sequence mapping. The former original target was the site where the pacing QRS was entirely consistent with IVT(Idiopathetic Ventricular Tachycardia) attack. And the latter original target was the site of in advance of earliest high frequency and low amplitude local potential on surface electrocardiogram QRS≥20ms, using activation sequence mapping. Results: Among 12 patients, the IVT originated from right ventricle in 2 patients, from left ventricle in 10 patients.

对12例正常心脏室速进行导管消融，采用起搏标测与激动顺序标测，前者以起搏时与室速QRS波型形态完全相同，后者以激动顺序标测法定位，以记录心动过速时较体表心电图QRS提前≥20ms的最早高频低振幅局部电位处为消融靶点，结果：12例患者室速起源部位分别为：右心室2例，左心室10例，疗效100%。

Most of the detected channels are characterized by low-amplitude reflections and is likely to be dominated by mudstones with interbedded thin sandstones.

根据地震剖面和相干时间切片时空分析，认为该水道主要有3期侵蚀和3期充填过程。

The result shows that the output amplitude and linearity of phase interpolator is primarily related to the difference between the two input phases.

分析结果表明相位插值器输出时钟的相位和幅度强烈地依赖于插值器输入时钟间的相位差，同时提出一种新的编码方法来补偿相位的非线性。

Since the most significant difference happened between the middle phase of expiration and the middle phase of inspiration, this result implies that it is the intrapulmonary pressure and the cardiac volume, but not the relative position of the heart and electrodes, which cause the variation of the amplitude of QRS complex.

其中QRS波的振幅在呼气中期最高在吸气中期最低，根据呼吸运动时肺容积及肺内压变化的规律，认为是由于胸腔压力和心室舒容积的改变，而不是心脏与电极间的相对位置的改变造成了QRS波振幅的变化。

Since the most significant difference happened between the middle phase of expiration and the middle phase of inspiration, this result implies that it is the intrapulmonary pressure and the cardiac volume, but not the relative position of the heart and electrodes, which cause the variation of the amplitude of QRS complex.

在一些情况下需要消除呼吸的影响，如高分辨心电图中的波形对齐［1］。这就要求对呼吸影响QRS波形的机制有深入的了解。有些研究通过数学模拟和观察体表电位图，认为呼吸造成心电图变异的主要原因是由心脏与电极的相对位置改变造成的［2，3］，并据此作了一些补偿方案。
