According to predefined inclusion and exclusion criteria, the relevant literatures were searched and qualified literatures were determined. Based on total number of electrocardiogram (ECG) examination and number of abnormal ECG in radiation group and control group, the heterogeneity test was employed by using effect size of OR (OR is odd ratio, it represents the ratio of exposure to disease risk and non-exposure to disease risk). Fixed effect model or random effect model was used for meta analysis. A total of 15 literatures met the inclusion criteria. Meta-analyses showed that the difference on ECG abnormality rate between the radiation group and the control group was statistical significant[OR=1.63, 95% CI (1.32, 2.02), p<0.00001]. It suggests that long term exposure to professionally low dose-ionizing radiation has significant influence on ECG abnormality risk in radiation workers.
