摘要本文对130例老年病人和55例正常人进行连续动态心电图（DCG）分析研究。所有被检者均采用双导AVIONICS 445A磁带式心电记录仪进行24小时连续监测，结果以660A AVIONICS心电扫描分析仪作快速及实时分析。老年病人年龄为65～102岁；正常人对照组为20～62岁。本文观察结果表明两组平均心率无明显差异，窦性心律并无随年龄增长而减慢、心率波动范围亦非变狭。130例老年病人中检出房性早搏123例（1～20，426次／24小时），其中多源性26例，阵发性房速78例（1～50阵／24小时）；室性早搏79例（1～30,015次／24小时），其中多源性19例，室性并行心律11例，阵发性短阵室速9例（1～27阵／24小时）。在对66例冠心病人与18例肺心病人对照分析：前者房早发生率为93.9%、后者83.3%，P<0.05；而室早之发生率前者为63.6%、后者50%，P>0.05；此外，检出了病窦综合征（SSS）5例（3.8%）。动态心电图观察病窦综合征不仅可以发现平均心率减慢，且可发现其特征性之心律失常，故DCG对SSS检出率较常规心电图为高，在这类患者中用DCG之另一优点可避 在老年病人中再行窦房结功能测定；还检出房扑和房颤共5例，其中阵发性3例。总之，以DCG分析老年病人心律失常，其结果颇为满意。

abstractsAnalysis of dynamic electrocardiography (DCG) in 130 aged patients and 55 normal subjects were made. The age of patients are between 65~102 years old and the normal control subjects are between 20~62 years. The results showed that the mean heart rates were not apparently different between the aged patients and the normal ones. In addition, we discovered that with the increased age the sinus heart rate was not decreased and the range of the heart rate did not become narrow. Premature atrial contractions were detected in 123 aged patients (1~20,426 PAC/24h), in whom multifocal pattern was found in 26, paroxysmal atrial tachycardia in 78 (1~50 paroxysms/24h). premature ventricular contractions were detected in 79 aged patients (1~30,015 PVC/24h), in whom multifocal pattern was found in 19, ventricular parasystole in 11, paroxysmal ventricular tachycardia in 9 (1~27 paroxysms/24h). After analysing the results of DCG recording in 66 aged patients with coronary heart disease and comparing with 18 aged patients with pulmonary heart disease, we discovered that the premature atrial contractions were detected in 93.9% of the former, and in 83.3% of the latter (P<0.05). However, the premature ventricular contractions were detected in 63.6% of the former, and in 50% of the latter (P>0.05). The sick sinus syndrome (SSS) was found in 5 patients (3.8%). Dynamic electrocardiographic recording in the patients with SSS not only showed decrease of the mean heart rate, but also the presence of its characteristic arrhythmias in various degrees. Moreover, the frequency of SSS detected with DCG is higher than with conventional ECG. Another advantage of using DCG to detect SSS is the avoidance of undergoing the tests for the function of the sino-atrial node in the aged patients. Atrial flutter and atrial fibrillation were found in 5 patients, in whom 3 were paroxysmal. Generally speaking, it can be concluded that the use of DCG in the evaluation of arrhythmias in the aged patients is more satisfactory.
