目的:观察老年心悸患者的动态心电图变化。方法:通过动态心电图分析老年心悸患者即心悸组及对照组与心律失常及心率变异性之间的关系。结果:心悸组SDNN及SDANN组降低(P<0.05),动态心电图与常规心电图检查心律失常的检出率比较有统计学意义(P<0.01),心悸组SDNN、SDANN降低。心律失常与心率变异性时域测值关系显示rMSSD增高,SDNN、SDANN降低(P<0.05或P<0.01)。结论:心悸本身并无特异性,但提示往往可能存在心律失常。
Objective: To observe the changes of ambulatory electrocardiogram in elderly patients with palpitation. Methods: The relationship between arrhythmia and heart rate variability in elderly patients with palpitations, heart palpitations and control group was analyzed by Holter monitoring. Results: The SDNN and SDANN groups in the palpitations group were decreased (P <0.05). The detection rates of ambulatory ECG and conventional electrocardiogram were significantly different (P <0.01). SDNN and SDANN in the palpitations group were decreased. The relationship between arrhythmia and heart rate variability showed that rMSSD increased and SDNN and SDANN decreased (P <0.05 or P <0.01). Conclusion: Palpitations are not specific in themselves, but suggest that arrhythmias can often be present.
