Abstract: Objective To explore the arrhythmia status and its related influencing factors in the physical examination population of Beijing Jishuitan Hospital, and to provide a reference for the prevention and treatment of arrhythmia. Methods The study focuses on the population who underwent a physical examination at a tertiary hospital in Beijing from January 2020 to October 2022. The basic information and physical examination data of all patients were collected, and the occurrence of arrhythmias in this group was analyzed by descriptive analysis, and univariate and multivariate Logistic regression analysis methods were used to analyze the factors affecting arrhythmia in the physical examination population. Results A total of 1 428 persons were examined in the hospital, of which there were 393 cases of arrhythmia, with an incidence rate of 27.52%. Multivariate Logistic regression analysis showed that age ≥ 60 years old （OR=4.651）, smoking （OR=4.586）, alcohol consumption （OR=3.691）, increased left atrial diameter （OR=2.418）, hypertension （OR=4.212）, hyperglycemia （OR=2.514）, overweight/obesity （OR=3.557）, abnormal uric acid （OR=3.575）, and hypokalemia （OR=2.002） were all risk factors for the occurrence of arrhythmia, while exercise （OR=0.504） and healthy diet （OR=0.763） were protective factors for the occurrence of arrhythmia. Conclusions The incidence of arrhythmia is high in the physical examination population. Medical staff should provide health guidance according to the related risk factors, and reduce the occurrence of arrhythmia through exercise, healthy diet, and other ways, to reduce the harm of arrhythmia to people's health.
