We describe the electrocardiographic changes during everyday activities recorded by ambulatory electrocardiographic monitoring in 67 patients with neurocirculatory asthenia. The findings were compared with the results of ambulatory monitoring in 33 healthy controls. We observed episodes of sinus tachycardia > 120/min unrelated to effort in 60 of the patients, 35 had frequent episodes of pronounced sinus arrhythmia, 16 showed transient ST depression, and six transient ST elevation. All these changes appeared during the patients' routine activities, without any unusual exertion and frequently at rest. Periods of sinus tachycardia and sinus arrhythmia were recorded from the patients during sleep. Cardiac arrhythmias, especially ventricular premature beats, were also much more common in those with neurocirculatory asthenia than in the control subjects. These findings indicate that ambulatory electrocardiographic monitoring provides important information on the electrocardiographic characteristics of patients with neurocirculatory asthenia and helps to establish this diagnosis in obscure cases.
我们描述了67例神经循环性无力症患者通过动态心电图监测记录的日常活动期间的心电图变化。将这些结果与33名健康对照者的动态监测结果进行了比较。我们观察到，60例患者出现与运动无关的窦性心动过速发作>120次/分钟，35例有频繁的明显窦性心律失常发作，16例出现短暂性ST段压低，6例出现短暂性ST段抬高。所有这些变化均出现在患者的日常活动期间，没有任何异常用力，且常在休息时出现。在患者睡眠期间记录到窦性心动过速和窦性心律失常。心律失常，尤其是室性早搏，在神经循环性无力症患者中也比对照组更为常见。这些发现表明，动态心电图监测为神经循环性无力症患者的心电图特征提供了重要信息，并有助于在疑难病例中确立该诊断。
