摘要

传统的时域测量方法(如心率)很难描述纤颤性心律。作者描述了在心内信号处理中不常用的两种测量方法;功率谱2 ~ 9hz区域的中位数频率(MF)和幅度平方相干(MSC)函数。这两个度量是正式定义的。MF是药物诱导心房颤动变化的有力指标，而MSC是心房和心室心律组织程度的指标

Median frequency and coherence measures of atrial and ventricular fibrillation

Fibrillatory rhythms are poorly characterized by traditional time-domain measures, such as rate. The authors describe two measures not commonly applied in intracardiac signal processing; the median frequency (MF) in the 2 to 9 Hz region of the power spectrum, and the magnitude-squared coherence (MSC) function. These two measures are formally defined. The MF is a robust measure of drug-induced changes in atrial fibrillation, and the MSC is a measure of the degree of organization of atrial and ventricular cardiac rhythms.<>
