单纯性肥胖儿童脉搏图变化及其机理探讨

Investigation of the change and mechanism on the pulsegram in the simple obese children

目的 :研究单纯性肥胖儿童脉搏图的变化及其机理。方法 :用 XG-E2 型血液循环测试仪描记 3 2例单纯性肥胖儿童 (肥胖组 )和 3 2例正常儿童 (正常组 )桡动脉脉搏图及三种血流动力学数据。结果 :肥胖组与正常组脉搏波形构成不一致( χ2 =11.89,P <0 .0 5 ) ,其中肥胖组波形以平波、弦波居多 (占 40 .6%和 3 4 .4% ) ,正常组波形以平波居多 (占 68.8% ) ,肥胖组心脏指数 ( CI)、平均动脉压 ( MAP)、总外周阻力 ( TPR)均高于正常组 ,差别有显著性。结论 :肥胖组脉搏波形以弦波居多 ( 3 4 .4% )与 CI,MAP,TPR升高有关。

Objective: It is to investigate the change and mechanism on the pulsegram in the simple obese children. Methods: The pulsegram on the radialis artery and the three data on the hemodynamics in 32 simple obese children (fatty group) and in 32 normal children (normal group) were described with an XG F 2 model surveying instrument of the blood circulation. Results: There is a different distribution on the waves between the fatty group and the normal group. Plain wave was 40.6% and bowstring wave was 34.4% in fatty group. Plain wave was 68.8% in normal group. Conclusion: The change on the pulsegram is related to increment of the CI, MAP and TPR in fatty group.
