【摘要】 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,ES₂,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。更多还原

【Abstract】 The ACG and CPW changes during isometric handgrip test were assessed in 30 normal subjects and 25 patients with positive ECG double two-step test in 13 cases and positive treadmill test in 12 cases. Data were obtained just before and after the handgrip, including a/EO, ES₂, PEP, PEPI, LVET, PEP/LVET and EF. All showed no significant difference between the patient and normal groups. The a/EO showed significant increase （p<0. 05） after handgrip test in patient group, with 9 cases （36％） having a/EO>15％, which might be a reflection of elevation of LVEDP after handgrip.The contours of the systolic contraction waves of the ACG in patient group after the handgrip test showed significant changes as compared with normal group. In the patient group, the mid-late systolic paradoxical bulges increased significantly after the handgrip; we termed the second peak after the E point as "X". XO/EO>1 meant the existence of the bulge. Before handgrip, none of the normal group showed XO/EO>1, while in patient group there were 5 cases presenting XO/EO>1. After handgrip, 3 cases of the normal group attained XO/EO>1, but in the patient group there were 19 cases （p<0.001）. The sensitivity was 76％ and specificity was 90％.更多还原
