观察了40例受试者吸烟前后心电图及心电频谱图的变化.结果表明,吸烟后心率较吸烟前平均增快7.4次/min(P<0.001),心电图除心率变化外未见其他改变;吸烟后有33例(82.5%)出现心电频谱图改变,以相干函数变化最明显,吸烟前阳性率为22.5%,吸烟后阳性率为57.5%(P<0.01),其他指标阳性率吸烟后均有不同程度增高.提示吸烟对心脏有确切的损害作用,戒烟对降低心脏病的发病率有重要的意义.
The changes of electrocardiogram and electrocardiogram before and after smoking were observed in 40 subjects.The results showed that after smoking, the heart rate increased 7.4 times / min (P <0.001) before smoking, and there was no other changes in electrocardiogram except heart rate. After smoking, 33 patients (82.5%) had ECG changes, the most obvious changes were in coherence function. The positive rate before smoking was 22.5% and the positive rate after smoking was 57.5% (P <0.01) Have increased to varying degrees.It is suggested that smoking on the heart has the exact damage, quit smoking to reduce the incidence of heart disease is of great significance.
