目的:寻找不同人群心电图的表现规律,探究心电图表现与心血管疾病的关系,为心血管疾病的防治提供参考依据。方法:对1 155例体检者按年龄、性别分组,对心电图的主要异常表现进行分析。结果:中老年组的异常心电图总检出率男、女性均明显高于青年组(P<0.01),但各组内男、女性的异常心电图总检出率比较差异无统计学意义(P>0.05);在异常心电图中,ST-T改变、各种期前收缩发生率,中老年组明显高于青年组(P<0.01),但各组内男、女性的发生率比较差异无统计学意义(P>0.05);中老年组、青年组男性窦性心动过缓发生率均较高,但两组比较差异无统计学意义(P>0.05)。结论:中老组心电图的异常检出率、ST-T改变、各种期前收缩发生率均高于青年组,这与中老年人易患心血管疾病有一定关系。
OBJECTIVE: To find out the regularity of electrocardiogram (ECG) in different population, to explore the relationship between electrocardiogram (ECG) and cardiovascular disease and to provide reference for the prevention and treatment of cardiovascular diseases. Methods: A total of 1 155 cases were divided into groups by age and sex to analyze the major abnormalities of ECG. Results: The total detection rate of abnormal ECG in middle and old age group was significantly higher than that in youth group (P <0.01), but there was no significant difference in the total detection rate of abnormal ECG between male and female in each group (P> 0.05). In abnormal electrocardiogram, ST-T changed, the incidence of various pre-term contractions was significantly higher in middle-aged and elderly groups than in youth group (P <0.01), but there was no significant difference in the incidence of male and female in each group (P> 0.05). The prevalence of sinus bradycardia in the middle-aged and elderly groups was higher, but there was no significant difference between the two groups (P> 0.05). Conclusion: The abnormal detection rate of ECG, the change of ST-T and the incidence of various types of premature rupture in middle-aged and old patients are higher than those in youth group, which is related to the susceptibility to cardiovascular disease in middle-aged and old people.
