Comparative Study
Achieving ventricular rate control in patients taking chronic beta-blocker therapy.
The objective of this study is to evaluate the difference in response to ventricular rate control with intravenous (IV) metoprolol compared to IV diltiazem in patients taking chronic beta-blocker therapy who present to the emergency department (ED) in atrial fibrillation (AF) with rapid ventricular rate (RVR). ⋯ The use of IV diltiazem was associated with a higher rate of successful response to rate control compared to IV metoprolol in patients in AF with RVR on chronic beta-blocker therapy, however the difference between groups was not statistically significant.

This study aimed to clarify the association between the crowding and clinical practice in the emergency department (ED). ⋯ Overcrowding in the ED might increase physicians' decision-making time and patients' length of stay, and more patients could be admitted to observation units or an inpatient department. The use of CT and laboratory examinations would also increase. All of these could lead more patients to stay in the ED.
