目的:分析鳀鱼腐败气体中毒对患者心电图的影响。方法:以荣成市石岛人民医院2010年6月至2019年6月收治的急性鳀鱼腐败气体中毒患者396例为研究对象，根据患者症状、体征的严重程度，将中毒患者分为轻度(107例)、中度(198例)、重度(91例)3个等级。采用日本光电1250P心电图机对中毒患者进行12导联心电图检查，并对结果进行分析比较。结果:396例鳀鱼腐败气体中毒患者中有211例心电图结果异常，心电图异常发生率为53.3%，轻度、中度、重度3组心电图异常率分别为52.3%(56/107)、51.5%(102/198)、58.2%(53/91)，组间比较差异无统计学意义(n P>0.05)。不同程度中毒患者的心电图异常表现多见窦性心动过缓、束支传导阻滞、QT间期延长、ST段下移等，轻度、中度、重度3组间比较差异有统计学意义(n P0.05). The most common abnormal ECG manifestations were sinus bradycardia, bundle branch block, QT interval prolongation, ST segment depression, etc. The differences of those above-mentioned manifestations among the three groups were statistically significant (n P<0.05).n Conclusion:The abnormal rate of ECG results is high in patients with anchovy putrefaction gas poisoning, and the abnormal changes of ECG results are related to the severity of poisoning.
