摘要:
探讨老年2型糖尿病无症状心肌缺血(SMI)患者的心电学特点。方法:随机选择24h动态心电图检测的老年单纯2型糖尿病患者70例(Ⅰ组)、2型糖尿病合并SMI患者55例(Ⅱ组)及健康老年对照者50例(Ⅲ组),对比Ⅰ组和Ⅱ组心律失常情况,并对其室性早搏发生部位进行分析,对比3组心率变异性(HRV)时域指标[24h窦性RR间期均值标准差(SDNN)、5min窦性RR间期均值标准差(SDANNIndex)、5min窦性RR间期标准差的均值(SDNNIndex)、24hRR连续差异均方的平方根(rMSSD)和相邻窦性RR间期差值>50ms的百分比(PNN50)]。结果:Ⅰ组和Ⅱ组房性早搏(χ2=0.509,P=0.475)、房性心动过速(χ2=0.086,P=0.769)发生率比较,差异无统计学意义;但室性早搏(χ2=9.478,P=0.002)、室性心动过速(χ2=2.458,P=0.117)发生率比较,差异有统计学意义。Ⅱ组左心室前壁及心尖部室性早搏发生率高于Ⅰ组(χ2=9.943,P=0.002)。3组HRV时域指标SDNN、SDANNIndex、SDNNIndex、rMSSD和PNN50比较,差异均有统计学意义(F为20.126、23.151、14.356、17.407和8.181,P均<0.05);且Ⅱ组rMSSD、PNN50与Ⅲ组比较,差异亦有统计学意义(P均<0.05)。结论:老年2型糖尿病SMI患者室性心律失常发生率增高,HRV降低,左心室前壁及心尖部室性早搏发生率高于单纯老年2型糖尿病患者。
Abstract:
To explore the feature of electrocardiology in old silent myocardial ischemia(SMI) patients with type 2 diabetes mellitus (T2DM).Methods:A total of 175 subjects were randomly divided into three groups.A total of 70 cases of old patients with fracture T2DM was group Ⅰ,55 cases of old patients with T2DM and SMI was groupⅡ,and 50 cases of old healthy was group Ⅲ according to 24 h dynamic electrocardiogram.The arrhythmia and localization of ventricular premature beats in Ⅰ and Ⅱ groups were contrasted and analyzed.The heart rate variability (HRV) indices SDNN,SDANN Index,SDNN Index,rMSSD,and PNN50 of each group were contrasted and analyzed.Results: The difference of atrial arrhythmia in group I and Ⅱ was not significant(atrial premature beats:χ2=0.509,P=0.475;atrial tachycardia:χ2=0.086,P=0.769). The difference of ventricular arrhythmia was significant between the two groups(ventricular premature beats: χ2=9.478,P=0.002; ventricular tachycardia:χ2=2.458,P=0.117). In group Ⅱ the rate of ventricular premature beats from left anterior wall and left ventricular apex was significant higher than that of group Ⅰ(χ2=9.943,P=0.002).The difference of SDNN,SDANN Index,SDNN Index,rMSSD,and PNN50 among the three groups were significant,respectively(F was 20.126,23.151,14.356,17.407,and 8.181,P<0.05).The difference of rMSSD and PNN50 in group Ⅱ and Ⅲ was significant(P<0.05).Conclusion: In SMI old patients with T2DM,the incidence of ventricular arrhythmia is high,and HRV is low. The rate of ventricular premature beats from left anterior wall and left ventricular apex is higher than that of old patients with T2DM.
