作者对１２４１例北方中老年患者心律失常的发生率、类型及其变化情况进行分析，并分为老年组和老年前期组进行比较。结果显示，两组差异不显著（Ｐ＞０．０５），仅在心房纤颤、室性早搏、左前分支阻滞（ＬＡＨ）三个方面，老年组较老年前期组略有增加，从统计学上看意义不大。提示，要降低心血管病的发病率，应从中青年开始采取预防措施，控制血脂和血压水平等，以减少诱发心血管病的危险因素。
The author analyzed the incidence, types and changes of arrhythmia in 1241 middle-aged and middle-aged patients in our country and divided them into the elderly group and the elderly group. The results showed that there was no significant difference between the two groups (P> 0.05). Only in the three aspects of atrial fibrillation, premature ventricular contractions and left anterior branch block (LAH), the elderly group slightly increased compared with the pre-senile group, Not meaningful on the point of view. Tip, to reduce the incidence of cardiovascular disease, young and middle-aged should take precautionary measures to control blood lipids and blood pressure levels, in order to reduce the risk of cardiovascular disease risk factors.
