地震可能增加血流动力学不稳定室性心动过速（HUSVTs）的风险。然而，目前尚不清楚这些心律失常是如何在地震期间触发的。回顾了四川成都华西医院心血管科在汶川地震后1个月及地震前1个月和2007年4月12日至7月11日2个控制期的病历资料。地震后1个月的HUSVT事件发生率高于2个对照期（67件/万人日vs 7件/万人日和14件/万人日，p = 0.000006和p = 0.0004）。地震月HUSVT事件多发生在下午时段，与强震活动的时间趋势一致，与控制期HUSVT事件的日分布模式不同。在由地震前入住CV科并在地震期间继续在CV科治疗的患者组成的亚群中，所有HUSVT事件都发生在地震后的间隔时间内，而地震前的间隔时间内没有HUSVT事件。无明确原因的低钾血症、急性心肌缺血和无缺血证据的心力衰竭与地震月份的HUSVT事件相关。综上所述，地震及其余震可触发住院心脏病患者HUSVT事件的发生。(C) 2009出版Elsevier Inc. （Am J Cardiol 2009;103:994-997）
Earthquake may increase the risk of hemodynamically unstable ventricular tachyarrhythmias (HUSVTs). However, it was unclear how these arrhythmias were triggered during the period of earthquake. Medical records of patients in the Cardiovascular (CV) Department of West China Hospital, Chengdu, Sichuan, China, during the month after the Wenchuan earthquake and the 2 control periods (1 month before the earthquake and April 12 through July 11, 2007) were reviewed. The HUSVT event rate/10,000 person-days was higher during the month after the earthquake than during the 2 control periods (67 events/10,000 person-days vs 7 and 14 events/10,000 person-days; p = 0.000006 and p = 0.0004, respectively). Most HUSVT events in the earthquake month occurred in afternoon hours, consistent with the temporal trend of strong seismic activities and different from the pattern of diurnal distribution of HUSVT events occurring in the control periods. In the subpopulation consisting of patients admitted to the CV Department before the earthquake who continued to be treated the CV Department during the earthquake period, all HUSVT events occurred during the interval after the earthquake in comparison to no HUSVT event during the interval before the earthquake. Hypokalemia without identifiable cause, acute myocardial ischemia, and heart failure without evidence of ischemia were associated with HUSVT events in the earthquake month. In conclusion, the earthquake and its aftershocks could trigger the occurrence of HUSVT events in hospitalized patients with heart disease. (C) 2009 Published by Elsevier Inc.
