This study was designed to analyze the value of 24 h dynamic electrocardiography (DCG) examination in the diagnosis of pulmonary heart disease (PHD).
Ninety cases of patients with PHD were included as the observation group, and 50 cases of healthy patients were enrolled as the healthy group. Both groups received DCG examination.
The proportion of ST depression and elevation as well as the magnitude and duration of ST depression differed significantly between the observation and healthy group ( < 0.05), and the magnitude of ST elevation in patients of the observation group with decompensated heart failure was greater than that of patients with compensated cardiac function and the healthy group ( < 0.05). The incidence rates of sinus bradycardia (SB), ventricular premature beats (VPB), paroxysmal ventricular tachycardia (PVT), and ventricular fibrillation (VF) in patients in the observation group with decompensated heart failure were higher than those of patients with compensated cardiac function and the healthy group ( < 0.05). The differences in standard deviation of the NN (R-R) intervals (SDNN) and standard deviation of average NN intervals (SDANN) between the three groups were significant, and the root mean square of successive RR intervals (RMSSD) of patients in the observation group with decompensated heart failure were lower than those of the healthy group ( < 0.05). The differences in deceleration capacity (DC), left ventricular ejection fraction (LVEF), and heart rate variability (HRV) between the three groups were significant ( < 0.05).
The results obtained by DCG examination can help clinical assessment of cardiac function in the decompensated or compensated stage, which can assist in judging the condition of PHD and guide clinical treatment.
本研究旨在分析24小时动态心电图（DCG）检查在诊断肺心病（PHD）中的价值。
纳入90例肺心病患者作为观察组，50例健康患者作为健康组。两组均接受DCG检查。
观察组与健康组之间ST段压低和抬高的比例以及ST段压低的幅度和持续时间差异有统计学意义（<0.05），观察组失代偿性心力衰竭患者的ST段抬高幅度大于心功能代偿患者和健康组（<0.05）。观察组失代偿性心力衰竭患者的窦性心动过缓（SB）、室性早搏（VPB）、阵发性室性心动过速（PVT）和心室颤动（VF）发生率高于心功能代偿患者和健康组（<0.05）。三组间NN（R-R）间期标准差（SDNN）和平均NN间期标准差（SDANN）差异有统计学意义，观察组失代偿性心力衰竭患者的连续RR间期均方根（RMSSD）低于健康组（<0.05）。三组间减速能力（DC）、左心室射血分数（LVEF）和心率变异性（HRV）差异有统计学意义（<0.05）。
DCG检查结果有助于临床评估失代偿期或代偿期的心功能，可辅助判断肺心病病情并指导临床治疗。
