本文报告25例心电图运动试验阳性患者及30例正常人作等容握力试验前后的心尖搏动图(ACG)及颈动脉脉波图(CPW)观察结果。发现ACG中a/EO,ICT,ES_2,IRT及CPW中收缩时间间期各项指标及EF均无特异性变化,但患者组握力试验后ACG波形有明显变化。以E点后第二波峰顶点作为“X”点,则握力后XO/EO>1者患者组显著高于正常组(P<0.001),敏感性为76％,特异性为90％,提示ACG在等容握力试验后XO/EO>1在心电图运动试验阳性患者有较高特异性。有可能作为冠心病的一种辅助诊断方法。并对其机理、操作方法及注意点作了探讨。
This article reports the results of 25 patients with positive electrocardiogram test and 30 normal persons before and after isopy holding capacity test of apical beating (ACG) and carotid artery pulse wave (CPW). ACG in the a / EO, ICT, ES_2, IRT and CPW systolic time interval of the indicators and EF no specific changes, but after the group grip strength test ACG waveform changes significantly. The point of the second peak after the E point was taken as “X” point. The patients with XO / EO> 1 after grip strength were significantly higher than those in the normal group (P <0.001), with a sensitivity of 76% and a specificity of 90% The XO / EO> 1 was more specific in patients with positive electrocardiogram test after isokinetic test. It may be used as an auxiliary diagnosis of coronary heart disease. And its mechanism, operation method and attention point are discussed.
