The association of ambient temperature with incidence of cardiac arrhythmias in a short timescale

The body response time and an association between the exposure to outdoor temperature and cardiac arrhythmia were not fully understood. Hence, we further investigated the association between ambient temperature and the exacerbations of arrhythmia symptoms on a short timescale using the emergency dep...

Description
Summary:The body response time and an association between the exposure to outdoor temperature and cardiac arrhythmia were not fully understood. Hence, we further investigated the association between ambient temperature and the exacerbations of arrhythmia symptoms on a short timescale using the emergency department (ED) visit data. We used a total of 17,088 arrhythmia-related ED visits in Seoul, from 2008 to 2011 and fitted the model adjusting for other meteorological variables and air pollutants under the case-crossover analysis with the same year–month time stratification. The association was presented as an odds ratio (OR) with a 95% confidence interval (CI) by a 5 °C decrease in the ambient temperature. The delay time (h) between exposure and the onset of arrhythmia exacerbation was considered with time blocks for every 3 h as 1–3 h, up to 118–120 h; and daily lags (1 day), from 25–48 h to 97–120 h, as a multi-time average of exposures. The overall association was increased at lag 4–6 h and the increased association was statistically significant at lag 40–42 h (OR 1.027, 95% CI 1.003–1.051) and the adverse association continued at 97–120 h (OR 1.053, 95% CI 1.027–1.080). However, the delay of several days between ambient temperature and body response should be further investigated considering the modification according to varied demographic characteristics or different environmental circumstances.
