To describe time to electrocardiogram (ECG) acquisition, identify factors associated with timely acquisition, and evaluate the influence of time to ECG on adverse clinical outcomes.
We measured the door-to-ECG time for emergency department patients enrolled in prospective chest pain registry. Clinical outcomes were defined as occurrence of myocardial infarction or death within 30 days of the visit.
Among patients with acute coronary syndrome (ACS), 34% and 40.9% of patients with non-ST-elevation ACS and ST-elevation myocardial infarction (STEMI), respectively, had an ECG performed within 10 minutes of arrival. A delay in ECG acquisition was only associated with an increase risk of clinical outcomes in patients with STEMI at 30 days (odds ratio, 3.95; 95% confidence interval, 1.06-14.72; P = .04).
Approximately one third of patients with ACS received an ECG within 10 minutes. A prolonged door-to-ECG time was associated with an increased risk of clinical outcomes only in patients with STEMI.
描述心电图（ECG）采集时间，确定与及时采集相关的因素，并评估心电图检查时间对不良临床结局的影响。
我们测量了纳入前瞻性胸痛登记研究的急诊科患者从就诊到进行心电图检查的时间。临床结局定义为就诊后30天内发生心肌梗死或死亡。
在急性冠状动脉综合征（ACS）患者中，非ST段抬高型ACS患者和ST段抬高型心肌梗死（STEMI）患者分别有34%和40.9%在到达后10分钟内进行了心电图检查。心电图采集延迟仅与STEMI患者30天时临床结局风险增加相关（比值比，3.95；95%置信区间，1.06 - 14.72；P = 0.04）。
约三分之一的ACS患者在10分钟内接受了心电图检查。就诊到心电图检查时间延长仅与STEMI患者临床结局风险增加相关。
