超声心动图评价围生期窦性心动过速孕妇心功能的价值

Research on heart function in pregnant women with sinus tachycardia evaluated with echocardiography

目的 分析围生期窦性心动过速孕妇的超声心动图特点并探讨其临床意义.方法 选取住院分娩窦性心动过速孕妇30例（试验组）和健康孕妇30例（对照组）,对比两组超声心动图检查结果及临床资料.结果 两组年龄、孕龄、血压、体质量等一般资料比较差异无统计学意义（P＞0.05）.试验组心率显著高于对照组[（123.20±13.23）次/min比（86.17±6.78）次/min],差异有统计学意义（P＜0.01）.试验组左心室后壁厚度及二尖瓣反流、三尖瓣反流、主动脉瓣反流发生率显著高于对照组[（10.23±1.30） mm比（8.79±1.90） mm,63.33％（19/30）比16.67％（5/30）、66.67％（20/30）比30.00％（9/30）、26.67％（8/30）比6.67％ （2/30）],左心室后壁运动幅度低于对照组[（8.07±1.00） mm比（9.26±1.71） mm],差异均有统计学意义（P＜ 0.01或＜0.05）.试验组左心室收缩和舒张功能参数与对照组比较差异均有统计学意义（P＜ 0.01或＜0.05）.结论 围生期窦性心动过速孕妇多合并超声心动图解剖参数及功能参数的改变,及时行超声心动图监测可以提供治疗依据.

Objective To investigate the characteristic and clinical value of echocardiography in pregnant women with sinus tachycardia.Methods Thirty pregnant women with sinus tachycardia （experiment group） and 30 healthy pregnant women （control group） were selected.The echocardiography results and clinical data were compared between the 2 groups.Results There were no statistical differences in age,gestational age,blood pressure,weight between the 2 groups （P 〉 0.05）.The heart rate in experiment group was significantly higher than that in control group [（123.20 ± 13.23） times/min vs.（86.17 ± 6.78） times/min],there was statistical difference （P 〈 0.01）.The left ventricular posterior wall thickness and the rates of mitral regurgitation,tricuspid regurgitation,aortic regurgitation in experiment group were significantly higher than those in control group [（10.23 ± 1.30） mm vs.（8.79 ± 1.90） mm,63.33% （19/30） vs.16.67% （5/30）,66.67%（20/30） vs.30.00%（9/30）,26.67%（8/30） vs.6.67%（2/30）],the left ventricular posterior wall motion amplitude was significantly lower than that in control group [（8.07 ± 1.00） mm vs.（9.26 ± 1.71） mm],there were statistical differences （P 〈 0.01 or 〈 0.05）.There were statistical differences in the indexes of left ventricular systolic function and diastolic function between the 2 groups （P 〈0.01 or 〈0.05）.Conclusion The anatomical indexes and function indexes of echocardiography in pregnant women with sinus tachycardia are used to change,and the echocardiography in time can provide the basis of treatment.
