自主性激动不能影响心率改变是病态窦房结综合征(SSS)病人的常见表现。正常的呼吸性窦性心律不齐由迷走神经调节,因而在SSS病人表现为减弱。本文对一组平均年龄为68岁具有症状的SSS病人,与75例同年龄组正常人进行对照试验。窦性心律不齐的程度,按常规12导联心电图所出现的下列数据而定:(1) R—R间期误差率(R—R间
Autonomic agitation does not affect heart rate changes are common in patients with sick sinus syndrome (SSS). Normal respiratory sinus arrhythmia is regulated by the vagus nerve and thus appears to be attenuated in SSS patients. In this paper, a group of SSS patients with an average age of 68 years with symptoms and 75 normal subjects in the same age group were controlled. The degree of sinus arrhythmia, according to the conventional 12-lead ECG appears the following data: (1) R-R interval error rate (R-R between
