肥胖对P波最大时限及离散度的影响
Effect of obesity on P wave dispersion
摘要
Abstract
Objective To study the effects of obesity on Maximum P-wave duration (Pmax) and P wave dispersion (Pd) in order to evaluate the potential mechanisms for atrial fibrillation (AF) development in Chinese obesity subjects Methods The study population consisted of 40 obese subjects and 20 age-and sex-matched normal weight controls. Pmax, minimum Pwave duration (Pmin), and Pd were carefully measured using a 12-lead electrocardiogram. Results There were no significant differences between the two groups regarding age, sex, history of hypertension or diabetes, and hyperlipidemia. Compared to controls, BMI, left atrial diameter (LAD) and interventricular septal thickness (IVS) were increased (P<0.05), while Pmax and Pd (P<0.01) were significantly prolonged in the obese group. Conclusion Our data suggest that obesity is associated with increased Pmax and Pd, may be associated with the development of AF.关键词
