窦性心动过缓(简称窦缓)是指窦性心律频率每分钟60次以下,是心电图检查最常用的指标之一。它既可由生理性因素引起,如安静、睡眠或经常参加体育锻炼者;也可由病理性因素如植物神经功能紊乱,或心脏本身受损等引起。不同职业危害与窦缓的关系,目前尚未见报道。本文对染料、炼钢、养路、制漆和电解铝等5个行业的1,032名作业工人,在体检的基础上,仅对心电图表现为窦缓者的资料进行了初步分析,现报道如下:
Sinus bradycardia (referred to as sinus slowly) refers to sinus rhythm frequency of 60 times per minute or less, is one of the most commonly used indicators of ECG. It can be caused by physiological factors, such as quiet, sleep, or often participate in physical exercise; also by pathological factors such as autonomic dysfunction, or damage to the heart itself caused. Different occupational hazards and slow sinus relationship has not been reported. In this paper, 1,032 workers in 5 industries including dye, steel making, road maintenance, paint making and electrolytic aluminum, based on the physical examination, only conducted a preliminary analysis on the data of electrocardiogram (ECG)
