急性一氧化碳中毒的心电图改变及分型

目的：探讨急性一氧化碳中毒时心电的变化规律，为临床提供患者的心脏受损情况和电生理变化的客观依据。方法：对131例急性一氧化碳中毒的住院患者进行心电图动态观察，直至心电图恢复正常或处于相对稳定状态。然后前后对比，逐项分析其心电图的变化特点，并归纳其改变类型。结果；经统计表明：（1）急性一氧化碳中毒可引起多种心电图改变，就其变化的形式，我们归纳为四种类型，即缺血型、损伤型1心律失常型和其它型，但以缺血型最为多见，占异常总数的45.71%。（2）急性一氧化碳中毒致心电图改变的发病率较高，为35.11%，且发病率及其变化程度与患者的年龄和中毒程度均呈正相关，（3）心电图的转归一般良好。结论：对急性一氧化碳中毒患者进行心电图检查方便易行、诊断迅速、结果可靠，从而对临床诊断和治疗以及预后判断很有帮助，所以应当作为常规检查项目。

ELECTROCARDIOGRAM CHANGES AND TYPE OF ACUTE CARBON MONOXIDE POISONING

Objectives: To investigate the pattern of electrocardiogram changes in patients with acute carbon monoxide poisoning and to provide clinical diagnosis with the objective basis of the damaged condition and electrophysiological changes of the heart. Methods: Dynamic electrocardiogram observation was performed in 131 patients with acute carbon monoxide poisoning until their electrocardiogrm returned to normal or were in stable situation. The characteristics of electrocardiogrm changes were one by one analysed and their types were induced. Results:Statistics showed: (1)Acute carbon monoxide poisoning can lead to various electrocardiogram changes. According to the patterns of changes, we induce them into 4 types, i. e. ischemic type, damaged type, arrhythmic type and other type. The ischemic type was most commonly encountered, them acount for 45. 71% of abnormal electrocardiogrm? (2) the incidence rate (35.11%) of electrocardiogm changes caused by acute carbon monoxide poisoning was high, and the incidence rate and the extent of electrocardiogrm changes were positively correlated with the age of patient and the extent of poisoning; (3) generally, the outcome of electrocardiogrms was good. Conclusions s Electrocardiogrm examination was convenient and was operated easily and diagnosis was rapid, results were reliable, thus it was very helpful to determine the clinical diagnosis, treatment and prognosis. Threfore, electrocardiogram shall be taken as a routine examination item in acute carbon monoxide poisoning.
