目的探讨60岁以上老年人冠心病心律失常及其昼夜节律的临床意义。方法应用动态心电图对320例老年冠心病患者心律失常以及昼夜节律进行监测并与对照组比较分析。结果两组患者心房及室性心律失常的发生率有显著性差异(P<0.01),而房性+室性心律失常的发生率差异无显著性(P>0.05),两组患者心律失常存在昼夜节律并各有规律。结论心律失常与窦房结功能减退有关,心律失常存在昼夜节律,临床应根据其节律进行治疗,以降低心脏性猝死率。
Objective To investigate the clinical significance of arrhythmia and circadian rhythm of coronary heart disease in the elderly over 60 years old. Methods 320 cases of elderly patients with coronary heart disease arrhythmia and circadian rhythm were monitored by dynamic electrocardiogram and compared with the control group. Results The incidence of atrial and ventricular arrhythmia was significantly different between the two groups (P <0.01), while there was no significant difference in the incidence of atrial and ventricular arrhythmia (P> 0.05). Arrhythmia was found in both groups Circadian rhythm and have regular. Conclusion Arrhythmia is related to dysfunction of sinus node. There is circadian rhythm in arrhythmia. Clinic should be treated according to its rhythm to reduce the rate of sudden cardiac death.
