观察32例高血压病及32例健康对照组心电图P波改变,结果显示高血压病P波异常相当普遍,以P_1波宽度及P/P-R段比值最为明显。在高血压病组中有7例仅有P波异常而无明显房室改变,提示P波异常可能为高血压病在心脏的最早期改变。
The changes of P wave in 32 cases of hypertension and 32 cases of healthy control group were observed. The results showed that the abnormal P wave of hypertension was quite common. The ratio of P 1 wave width and P / P-R segment was the most obvious. In the hypertensive group, there were 7 cases of P wave abnormalities without obvious atrioventricular changes, suggesting that P wave abnormalities may be the earliest changes in the heart of hypertension.
