摘要目的 通过对加勒比海3国医疗服务中心电图检查结果进行统计、分析,了解所服务地区各类人员异常心电图检出情况及相关原因.方法 根据心电图检查结果分类、分组记录,并进行统计和回顾性分析.结果 华人华侨心电图异常检出率(39.3％)低于加勒比海3国患者,差异有统计学意义(P＜0.05),与良好的生活习惯和自我保健意识有关；加勒比海3国患者异常心电图位居首位的是ST-T改变,这与当地的饮食结构有关；中老年组患者异常心电图检出率(96.5％)明显高于青年组(34.3％),差异有统计学意义(P＜0.01)；各组内男、女异常检出率比较差异无统计学意义(P＞0.05),这2组中ST-T改变、左心室高电压、房室阻滞、陈旧性心肌梗死的发生率中老年组明显高于青年组,说明心电图异常改变与老龄化程度有关.结论 心电图检查在加勒比海3国医疗服务中具有重要的辅助检查作用.

abstractsObjective To analyze ECG statistical data obtained during medical tour in the 3 Caribbean countries,and to reveal the detectable rate and reasons for abnormal ECGs among various kinds of people in these regions.Methods The recorded ECG data were classified and divided into subgroups,then,statistical and retrospective analyses were made accordingly.Results The detectable rate of abnormal ECGs among the Chinese or overseas Chinese was lower than that of local residents,with significant difference,when comparisons were made between them (P ＜ 0.05).This was perhaps due to good life habit and awareness of self health care.The most prominent abnormality in ECG among the local residents in the 3 Caribbean countries was the change in ST-T segment,which might be related with their diet.The abnormal ECG detectable rate of the mid-and-old-aged group(96.5％) was significantly higher than that of the young-aged group (34.3％),with statistical significance (P ＜ 0.01).However,no significant differences could be detected in the abnormal detectable rates between the male and the female of various groups (P ＞ 0.05),when comparisons were made between them.The incidence of ST-T change,left ventricular high voltage,atrial-ventricular conduction block and remote cardiac infarction in the mid-and-old-aged group was obviously higher than that of the young-aged group,indicating that abnormal change in ECG was closely related with the senior age.Conclusions ECG monitoring was an important accessory tool in the fulfillment of medical service delivered to residents in the 3 Caribbean countries.
