[AF-FORUM] 178E 房颤心率变异性评价－Buchner医师

[AF Symposium]

尊敬的Moga医生
我对将ULF功效归因于窦房结功能表示怀疑。有以下两 
方面原因：

1.超低频率指频率介于0～0.003 Hz（据我所知）。因此 
时间窗为50分钟或更长。什么样的窦房结功能能有这 
么长的时间窗？
2.ULF有因血流速度描记图不稳定而使相关图像失真的 
倾向。尤其是当均值发生暂时性变化时。
致敬！

178E Evaluation of HRV in AF. Dr. Buchner
Dear Dr Moga,
     I have doubts about attributing the ULF power to sinus node  
functionality. Two reasons:
1. ULF is 0 Hz to 0.003 Hz (as far as I know). Thus the time scale is  
50 minutes and longer. What kind of sinus node function would have  
such a long time scale?
2. ULF is very prone to distortions related e.g. with  
nonstationarities in the tachogram taken into consideration.  
Especially for temporarily changes of mean value.
