摘要
目的探讨老年人器质性心脏病室性早搏的特点。方法对照分析了132例老年人器质性心脏病组引起的室性早搏及94例老年非心脏病组(对照组)室性早搏的心电图特点。结果老年心脏病组室性早搏起源于左室98例,起源于右室34例;对照组起源于左室20例,起源于右室74例。老年人心脏病组室性早搏QRS波振幅<20mV者占67.4%,时限>0.12s者占77.3%,有切迹或呈错折波占87.1%。与对照组比较有显著差异(P<0.05)。结论老年人心脏病室性早搏多起源于左室,QRS波振幅<20mV,时限>0.12s,形态有切迹或错折波。
Objective To explore the electrocardiographic （ECG） characteristics of ventricular premature contractions （VPCs） in the elderly with organic heart diseases. Methods The ECG of 132 elderly patients with VPCs related to organic heart diseases and 94 control subjects with VPCs unrelated to organic heart diseases were observed. Results In patients with organic heart diseases ,there were 98 cases of VPCs originated from left ventricle, and 34 from right ventricle. By contrast,only 20 controls had VPCs originated from left ventricle,whereas 74 from right ventricle. 68.2% ,77.3% ,and 87, 2% of elderly patients were observed R-amplitude less than 20 mV, QRS duration longer than 0, 12 s, and notched QRS, respectively. The differences were significant as compared to controls （P 〈 0.05 ）. Conclusions Originating from left ventricle,R-amplitude less than 20 mV,QRS duration longer than 0. 12 s,and notched QRS can be regarded as the ECG characteristics of VPCs related to organic heart diseases in the elderly.
