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. ⋯ 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.

Randomized Controlled Trial
Albuterol nebulized in heliox in the initial ED treatment of pediatric asthma: a blinded, randomized controlled trial.
A prospective blinded, randomized controlled trial was undertaken to compare the initial response of albuterol nebulized in heliox or control in the treatment of moderately severe asthma in children presenting to a pediatric ED. ⋯ Our results demonstrate that albuterol nebulized with heliox offered no clinical benefit over standard therapy in the initial treatment of moderately severe asthma in the ED.

Current guidelines suggest that most patients who present to an emergency department (ED) with chest pain should be placed on a continuous electrocardiographic monitoring (CEM) device. We evaluated the utility of CEM in ED patients with chest pain. ⋯ Routine CEM in low-risk ED patients with chest pain results in an excessive number of alarms, most of which require no change in management. In these patients, the benefit of CEM may be limited, and given that 99.4% of alarms were false, current CEM technology needs to be improved.

We sought to assess the proportion of ED patients with an electronically detected S(3) or S(4), determine the relation of these heart sounds to heart failure (HF), and analyze how the proportion changes with ED treatment. ⋯ This study suggests the proportion of patients with an electronically detected S(3) in HF is more than 50%, and that its presence is affected by prior treatment with diuretics or vasodilators.
