The use of automated external defibrillators (AEDs) by lay rescuers can reduce the time to defibrillation, improving survival after out-of-hospital cardiac arrest. However, some people have hearing defects that can prevent them from understanding the AED verbal prompts. Moreover, even rescuers with normal hearing function may not easily understand the AED verbal prompts when operating in a noisy environment. This study was designed to assess the capability of rescuers to defibrillate effectively using an AED which included visual prompts. ⋯ This study demonstrates that untrained deaf rescuers can use AEDs appropriately providing that the defibrillator has visual instructions. Training improves defibrillator use and reduces time to defibrillation.

Among the fatal vascular complications associated with autosomal dominant polycystic disease (ADPKD), ruptured intracerebral aneurysm and ruptured abdominal aortic aneurysm are widely known. However, there are few reports on the dissecting thoracic aortic aneurysm as a fatal complication of ADPKD. We report a case of a 58-year-old man with a history of ADPKD who presented to the emergency department with out-of-hospital cardiac arrest. ⋯ The surgical specimen of the aorta showed cystic medial necrosis. This rare case emphasizes the need to consider such a diagnosis in a patient with ADPKD who presents to the emergency department with sudden cardiac arrest. In addition, the histological finding indicates the aetiological role of a collagen defect in addition to chronic hypertension in the pathogenesis of aortic dissection in ADPKD patients.

A short and effective training programme is an essential prerequisite for the use of automated external defibrillators (AED) by EMS providers and first responders. We evaluated a 3-h AED course based on the ERC requirements. ⋯ The majority of police officers can be trained to use an AED safely and effectively within a 3-h AED course. During this course, they also improve on their BLS skills. Successful completion of the course depends in part on the student characteristics.

The potential impact of efforts to improve the chain of survival for out-of-hospital sudden cardiac arrest (SCA) is unclear in part because estimates of the incidence of treatable cases of SCA are uncertain. The aim of the investigation was to determine a representative national incidence of emergency medical services (EMS)-treated all-rhythm and ventricular fibrillation (VF) SCA as well as survival. ⋯ The results provide a framework to assess opportunities and limitations of EMS care with regard to the public health burden of SCA.
