目的心房颤动（AF）是最常见的持续性心律失常，但其在普通人群中的发病率却很少。更稀少的是关于房颤的一个重要种类，阵发性房颤的信息。本研究的目的是评估每年新发症状性阵发性房颤病例的频率（“发病率”），并比较慢性AF患者的其他流行病学特征。方法和结果在4年的时间里，我们进行了一项前瞻性，在特定地理区域内对AF病例进行基于人群的调查，已知人群规模按年龄和性别分层。身份来源是为该地区服务的两家医院和所有初级保健机构。房颤持续时间少于7天的患者被定性为阵发性：房颤和所有其他慢性房颤。在研究期间，我们确定了1551例慢性房颤患者（51.7%男性，平均年龄71 ± 10.4岁，48.3%女性，平均年龄73.1 ± 10.8岁）和443例阵发性房颤患者。AF（59.6%男性，平均年龄59.6 ± 13.3岁，40.4%女性，平均年龄65.2 ± 10.1岁）。分别有15.6%和32.3%的慢性和阵发性AF患者没有基础心血管疾病。阵发性房颤新发病例的年平均发生率为6.2/万/年，高于对照组（P
Aim Although atrial fibrillation (AF) is the most commonly sustained arrhythmia, information about its incidence in the general population is sparse. Even more sparse is information on an important variety of AF, paroxysmal AF. The aim of this study is to assess the frequency of new cases of symptomatic paroxysmal AF per year ('incidence') in a general unselected population and to compare other epidemiological features with chronic AF patients.Methods and Results Over a 4 year period, we conducted a prospective, population-based survey of cases of AF in a defined geographical area with a known population size stratified for age and sex. Sources of identification were the two hospitals which serve the area and all the primary care settings. Patients with AF of less than 7 days duration were characterized as paroxysmal: AF and all others as chronic AF. During the study period we identified 1551 patients with chronic AF (51.7% male, mean age 71 +/- 10.4 years and 48.3% females, mean age 73.1 +/- 10.8 years) and 443 patients with paroxysmal. AF (59.6% male, mean age 59.6 +/- 13.3 years and 40.4% female, mean age 65.2 +/- 10.1 years). There was no underlying cardiovascular disease in 15.6% and 32.3% of patients with chronic and paroxysmal AF, respectively. The mean annual occurrence of new cases of paroxysmal AF was 6.2/10 000/year, and was higher (P
