铅能导致实验动物心电图异常,但铅对人心脏自主神经系统的影响未见报道。作者对172名男性铅作业工人进行了横断面调查,以了解铅作用于心脏自主神经系统而导致心电图R-R间期值减小,并判断这种减小的程度与血铅水平之间的剂量-反应关系。
Lead can lead to ECG abnormalities in experimental animals, but the impact of lead on human autonomic nervous system has not been reported. The authors conducted a cross-sectional survey of 172 male lead workers to understand the effect of lead on the autonomic nervous system of the heart leading to a decrease in the RR interval of the electrocardiogram and to determine the dose- Reaction relationship.
