Case Reports
Unnecessary shock from an implantable cardioverter-defibrillator following transcutaneous pacing.
As the population ages and cardiovascular disease becomes more prevalent, an increasing number of patients are receiving implantable cardioverter-defibrillators (ICDs). When these patients present to the emergency department, it is imperative that physicians are not only aware of the possible underlying medical issues that may have precipitated their admission but should also have a good understanding of the potential interactions that any medical intervention may have on the patient's device. We discuss a case in which a patient known to have an ICD in situ was transcutaneously paced for the management of bradycardia, leading to an unnecessary shock.

Observational Study
Drowning: an overlooked cause of out-of-hospital cardiac arrest in Canada.
Drowning is a major public health concern, yet little is known about the characteristics of drowning patients. The objectives of this study were to describe the demographic and clinical characteristics of out-of-hospital cardiac arrest (OHCA) attributed to drowning in Ontario and to compare the characteristics of OHCA attributed to drowning to those of presumed cardiac etiology. ⋯ Significant differences exist between OHCA of drowning and presumed cardiac etiologies. Most drownings are unwitnessed, occur in public locations, and present with nonshockable initial rhythms, suggesting that treatment should focus on bystander CPR. Future initiatives should focus on strategies to improve supervision in targeted locations and greater emphasis on bystander-initiated CPR, both of which may reduce drowning mortality.

Minor head trauma in young children is a major cause of emergency department visits. Conflicting guidelines exist regarding radiologic evaluation in such cases. ⋯ Canadian emergency physicians have a wide variation in skull radiography ordering in young children with minor head trauma. This variation, along with the need expressed by physicians, suggests that further research to develop a clinical decision rule is warranted.
