本文研究了临床诊断为早期心衰的老年病人30例;冠心病心功能正常者30例;无心肺疾病者30例;握力负荷后的心率变化。结果表明早期心衰组握力负荷后比另外两组心率有较明显的增加(p<0.01);心率恢复时间明显延长(P<0.01)。另两组握力负荷后心率增加较少;且心率迅速下降到负荷前水平;随之进一步下降后逐渐恢复到握力负荷前心率水平。因此握力试验可作为早期心请简便的可靠的诊断方法。
In this paper, 30 cases of elderly patients with clinical diagnosis of early heart failure; 30 cases of normal heart function in patients with coronary heart disease; 30 cases without heart and lung disease; changes in heart rate after grip load. The results showed that the heart failure rate in early heart failure group was significantly higher than that in the other two groups (p <0.01), and the recovery time was significantly longer (P <0.01). In the other two groups, the increase of heart rate after Grip load was less, and the heart rate dropped rapidly to the pre-load level. With the further decline, the heart rate gradually recovered to the level before Grip load. Therefore, the grip test can be used as an early heart, easy and reliable diagnostic method.
