目的分析24 h动态心电图>1.5 s长RR间期的常见病因及主要心电图改变。方法对我院接受24h动态心电图检查伴>1.5s长RR间期的患者598例的临床资料进行统计分析。结果三组患者的性别比较差异均无统计学意义(p>0.05),男性的长RR间期发生率均显著高于女性(p<0.05);C组患者的年龄、长RR间期发生率显著高于A组、B组(p<0.05),而B组患者的年龄、长RR间期发生率又显著高于A组(p<0.05)。598例患者中,在病因方面,97例为冠心病+糖尿病+高血压,75例为冠心病+糖尿病,69例为糖尿病+高血压,58例为单发糖尿病,56例为冠心病,50例为肺心病,42例为急性心肌梗死,31例为高血压,31例为脑血管病,15例为病窦综合征,15例为晕厥待查,13例为颈段脊髓损伤,11例为风心病,10例为心肌病,6例为病毒性心肌炎,5例为甲状腺功能亢进,8例为特发心律失常,13例正常,>1.5s长RR24h分布5例发生在06:00~22:00,341例发生在23:00~05:00,252例发生在22:00~06:00,分别占总数的0.84%、57.02%、42.14%。结论 24 h动态心电图能够对RR间期进行长程检测,性别、年龄、发生时间及病因等均对其造成直接而深刻的影响。
Objective To analyze the common etiologies and major electrocardiographic changes of the RR interval of 24 h ambulatory ECG> 1.5 s. Methods The clinical data of 598 patients who underwent 24h Holter examination with> 1.5s RR interval in our hospital were analyzed statistically. Results There was no significant difference in sex between the three groups (p> 0.05). The incidence of long RR interval in males was significantly higher than that in females (p <0.05). The incidence of long RR interval in group C (P <0.05), while the incidence of RR and RR in group B was significantly higher than that in group A (p <0.05). Of the 598 patients, 97 were coronary heart disease + diabetes + hypertension, 75 were coronary heart disease + diabetes, 69 were diabetes mellitus + hypertension, 58 were solitary diabetes mellitus, 56 were coronary heart disease, 50 were coronary heart disease, Cases of pulmonary heart disease, 42 cases of acute myocardial infarction, 31 cases of hypertension, 31 cases of cerebrovascular disease, 15 cases of sick sinus syndrome, 15 cases of syncope, 13 cases of cervical spinal cord injury, 11 cases 10 cases of cardiomyopathy, 6 cases of viral myocarditis, 5 cases of hyperthyroidism, 8 cases of idiopathic arrhythmia, 13 cases of normal,> 1.5s long RR24h distribution in 5 cases occurred at 06: 00 ~ 22: 00,341 cases occurred between 23:00 and 05:00, and 252 cases occurred between 22:00 and 06:00, accounting for 0.84%, 57.02% and 42.14% of the total, respectively. Conclusions The 24 h ambulatory electrocardiogram can detect the RR interval for a long time, and the gender, age, time of occurrence and etiology all have a direct and profound effect on it.
