Respiratory distress and tachycardia are common presenting complaints in infants and young children, and evaluation typically focuses on respiratory infections. Tachydysrhythmias causing heart failure are rare and can be difficult to diagnose in young children, but are reversible if recognized and treated early. ⋯ We discuss a 7-week-old female infant who presented with respiratory distress and persistent tachycardia. Evaluation revealed severe cardiac dysfunction with an underlying atrial flutter discovered on electrocardiography after adenosine administration. Rate control by synchronized electrocardioversion resulted in resolution of symptoms and restoration of cardiac function, confirming the diagnosis of atrial flutter-induced cardiomyopathy. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: Persistent or inappropriate tachycardia in a young child should not be dismissed and underlying dysrhythmia should be considered.

Observational Study
Focused Transesophageal Echocardiography by Emergency Physicians is Feasible and Clinically Influential: Observational Results from a Novel Ultrasound Program.
Emergency physicians frequently employ transthoracic echocardiography (TTE) to assist in diagnosis and therapy for patients with circulatory failure or arrest. In critically ill patients, transesophageal echocardiography (TEE) offers several advantages over TTE, including reliable, continuous image acquisition and superior image quality. Despite these advantages, TEE is not widely used by emergency physicians. ⋯ From our analysis of a single-center experience, ED-based TEE showed a high degree of feasibility and clinical utility, with a diagnostic and therapeutic influence seen in the majority of cases. Focused TEE demonstrated strongest uptake among intubated patients with either undifferentiated shock or cardiac arrest.

The literature regarding rhabdomyolysis secondary to illicit drug use is sparse. Clenbuterol is a bronchodilator approved for veterinary use, which in high doses can increase protein deposition and lipolysis similarly to anabolic steroids, and is thereby abused for bodybuilding and weight loss effects. Clenbuterol has previously been described in case reports to be cardiotoxic, with patient presentations similar to overdoses of sympathomimetic substances, but reports of rhabdomyolysis are limited to a single case series in horses. ⋯ We report the first case of rhabdomyolysis secondary to clenbuterol in a human. Our patient used clenbuterol for muscle-building effects in addition to exercise for multiple days prior to presentation. The patient's chief complaint at Emergency Department (ED) presentation was discolored urine. Workup for rhabdomyolysis was initiated, and an initial creatine kinase was measured at 122,933 units/L. Our patient's rhabdomyolysis was successfully treated with supportive therapy, and the patient was eventually discharged to home with no identifiable disability. The patient's kidney function remained at baseline, and no acute kidney injury was experienced secondary to rhabdomyolysis. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: Patients presenting to the ED may have been unintentionally exposed through cutting of illicit substances or through intentional use in bodybuilding. Clenbuterol has well-described cardiotoxic effects, and we report the additional toxicity of rhabdomyolysis with its use.

Comparative Study
Are Discrepancies in Waiting Time for Chest Pain at Emergency Departments between African Americans and Whites Improving Over Time?
One of the Healthy People 2010 goals was to eliminate racial disparities in the U.S health system. To date, we have limited knowledge about the impact of Healthy People on racial disparities at emergency departments (EDs). ⋯ Among patients presenting to the ED with symptoms suggesting ACS, AA compared to whites waited longer to receive care. In addition, this difference in waiting time persisted during the study period, even after the implementation of the Healthy People 2010 initiative. Additional research is warranted to investigate the underlying reasons for unequal care offered to AAs at EDs and the implications on disease outcome.
