老年人Ptf_(V_1)与左房增大、P波离散度的相关性分析

Analysis of the correlation between Ptf_(V_1) 、left atrial enlargement and P-wave dispersion in elderly people

目的探讨老年人PtfV1异常与左房增大的相关性。方法选择60岁以上老年人PtfV1异常(≤-0.04mm.s)102例(A组),并以PtfV1正常(>-0.04 mm.s)102例为对照,观察二维多普勒超声心动图(UCG)描记心脏形态结构及心功能参数,和心电图P波离散度(Pd)。结果 A组LAD(45.2±7.1mm)、LVEDd(48.4±5.0mm)、E/A<1(占60.78%);B组LAD(34.1±4.4mm)、LVEDd(44.9±4.9mm)、E/A<1(占35.29%),两组呈显著差异(P<0.01)。Pd在A组与B组间存在显著差异(39.4±9.9 VS 31.6±8.2,P<0.01),LAD与Pd呈正相关性(r 0.530)。结论 PtfV1异常,Pd增大可作为左房内径增大及早期心功能障碍的判断指标,有一定的参考价值。PtfV1的检测简便、重复性好,费用便宜,尤其适用于基层医院对老年人预防和长期治疗的监测。

Objective To study the elderly terminal force of P wave in lead V1（PtfV1） abnormal and left atrial enlargement and P-wave dispersion relevance.Methods 102patients with PtfV1 anomalies（PtfV1≤-0.04 mm·s） and 102patient PtfV1 nomalies（PtfV1〉-0.04 mm·s） in elderly people more than 60 years old.Observation of cardiac morphology and cardiac function parameters in two-dimensional Doppler Echocardiography and P-wave dispersion on the ECG.Results LAD（45.2±7.1mm）、LVEDd（48.4±5.0mm）、 E/A1（占60.78%）in PtfV1 abnormal patients,higher than PtfV1 normal patients（LAD 34.1±4.4mm、 LVEDd 44.9±4.9mm、E/A〈1 占35.29%） with significant difference,and P-wave dispersion is higher with PtfV1 abnormal than normal（39.4±9.9 VS 31.6±8.2,P〈0.01）,showed that the relationship of both correlated positively（r 0.530）.Conclusion PtfV1 abnormalities,Pd increases on ECG as left atrial enlargemet and early cardiac dysfunction in the judgments of indicators,there is a certain reference value.PtfV1 detection is simple,good repeatability and low cost,particularly in Community Hospital for the long-term treatment to prevent monitoring in the elderly.
