本研究旨在确定台北细颗粒物（PM2.5）水平与心律失常急诊室（ER）就诊次数之间是否存在关联。本研究收集台北市2006-2010年间因心律失常及环境空气污染的急诊人次资料。使用病例交叉方法估计急诊就诊的相对风险（RR），控制天气变量、一周中的哪一天、季节性和长期趋势。对于单一污染物模型（未对其他污染物进行调整），在温暖的天气（bbb23℃）和凉爽的天气（< 23℃），ER心律失常就诊次数的增加与PM2.5显著相关，四分位数范围的上升分别与心律失常ER就诊次数升高10% （95% CI = -15%）和4% （95% CI = 0-8%）相关。在双污染物模型中，无论在温暖天和凉爽的天气中，纳入二氧化硫（SO2）或臭氧（O-3）后，PM2.5水平仍然显著。这项研究提供的证据表明，较高水平的PM2.5会增加因心律失常而就诊的风险。
This study was undertaken to determine whether there was an association between fine particles (PM2.5) levels and number of emergency room (ER) visits for cardiac arrhythmias in Taipei, Taiwan. ER visits for cardiac arrhythmias and ambient air pollution data for Taipei were obtained for the period 2006-2010. The relative risk (RR) of ER visits was estimated using a case-crossover approach, controlling for weather variables, day of the week, seasonality, and long-term time trends. For the single-pollutant model (without adjustment for other pollutants), increased numbers of ER cardiac arrhythmia visits were significantly associated with PM2.5 on both warm days (>23 degrees C) and cool days (< 23 degrees C), with an interquartile range rise associated with a 10% (95% CI = -15%) and 4% (95% CI = 0-8%) elevation in number of ER visits for cardiac arrhythmias, respectively. In the two-pollutant models, PM2.5 levels remained significant after inclusion of sulfur dioxide (SO2) or ozone (O-3) on both warm and cool days. This study provides evidence that higher levels of PM2.5 increase the risk of number of ER visits for cardiac arrhythmias.
