The relationship between P-wave maximum duration and P-wave dispersion with echocardiographic parameters were analyzed.
分析P波最大时限和P波离散度与超声参数之间的相关关系。
Therefore the maximum of the radial energy during the P-wave arrive appears in the direction of the first singular vector.
证明了资料矩阵的总能量可用奇异值的平方和来表达，以及P波到达的径向能量最大值在第一奇异向量方向出现。
Methods: We measured the maximum P-wave duration and P-dispersion from the 12-lead surface electrocardiogram of 40 patients with IPAF and 40 age-matched healthy control subjects.
方法：对确诊IPAF病例和年龄匹配的健康人各40例，测量体表心电图12导联最大P波时限及P波离散度。
