Most of the irregularities are sinus bradycardia, sinus irregularity, and ST-T irregularity. These suggest the relationship between the abnormal ECG and the contact with organophosphorus pesticides. 主要改变为窦性心动过缓,窦性心律不齐,ST&T异常,说明心电图与异常接触有机磷衣药有关,应加强防护措施。
Among the abnormal ECG, the positive rates of sinus bradycardia, sinus irregularity and ST-T changes of the observed group were respectively significantly higher than that of the control group ( P < 0.01). 异常心电图中观察组窦性心律不齐、ST-T改变和束支传导阻滞分别明显高于对照组(均有P<0.01)。
