title: [Association between occupational stress and electrocardiographic abnormalities in employees].
abstract: OBJECTIVE
  To investigate the influence of occupational stress on electrocardiographic features in employees.
  
  
  METHODS
  In September 2014, a total of 186 employees in a solar photovoltaic company underwent the evaluation of occupational stress, and the changes in electrocardiographic findings were recorded.
  
  
  RESULTS
  The abnormal rate of electrocardiographic findings showed significant differences between different age groups(P<0.05), and the employees older than 50 years had the highest abnormal rate(34.0%). Among the study subjects aged 41-50 years, those with a high score of job responsibility and burden had a higher abnormal rate of electrocardiographic findings than those with a low score(24.3% vs 6.3%); among the study subjects older than 50 years, those with a high risk level had a higher abnormal rate of electrocardiographic findings than those with a low risk level(50.0% vs 22.6%). Among the study subjects older than 50 years, those with a high score of mental health had a significantly lower abnormal rate of electrocardiographic findings than those with a low score (8.3% vs 55.2%, P<0.05); the employees with high scores of physical complaint and daily stress had a higher abnormal rate of electrocardiographic findings than those with low scores of physical complaint and daily stress (52.2% vs 20.0%, P<0.05; 50.0% vs 22.6%, P<0.05). The unconditional multivariate logistic stepwise regression analysis showed that old age was the risk factor for the high abnormal rate of electrocardiographic findings (OR= 1.076, P=0.013), and that mental health was the protective factor for the abnormal rate of electrocardiographic findings(OR=0.356, P=0.017).
  
  
  CONCLUSIONS
  Occupational stress is the risk factor for abnormal electrocardiographic findings, and the abnormal rate of electrocardiographic findings tends to increase with the increasing severity of occupational stress.
