A 36-year-old man started to climb Mount Fuji (3776m above sea level: ASL), from the Gotemba new fifth station (2400m ASL). He had no significant medical history, and this was his first attempt to climb such a high mountain. He began feeling chest discomfort but continued to climb. When he reached the ninth station of the mountain (3600mASL), he lost consciousness. One individual immediately provided basic life support using an automated external defibrillator (AED) that was located in the station. After electroshocks, he regained consciousness...

Under the Italian Law "Legge Balduzzi", which was issued after the sudden cardiac death of professional athletes Pier Mario Morosini and Vigor Bovolenta in 2012, the presence of an automated external defibrillator (AED) and personnel trained to perform cardiopulmonary resuscitation must be available in every Italian sports facility from 2016. In 2015 the national and local press reported 123 cases of sudden cardiac arrests (SCA) occurring in Italian sport facilities, corresponding to an estimated ≈0.2-0.4% of all SCA and to ≈0...

BACKGROUND: Automated external defibrillators can provide life-saving therapies to treat ventricular fibrillation. We developed a prototype unit that can deliver a unique shock waveform produced by four independent capacitors that is delivered through two shock vectors, with the rationale of providing more robust shock pathways during emergent defibrillation. We describe the initial testing and feasibility of this unique defibrillation unit, features of which may enable downsizing of current defibrillator devices...

OBJECTIVES: Nurses and respiratory therapists are seldom allowed to use automated external defibrillators (AED) during in-hospital cardiac arrest. This can result in significant time delays before defibrillation occurs and lower survival for cardiac arrest victims. We sought to identify barriers and facilitators to AED use by nurses and respiratory therapists. METHODS: We conducted semi-structured qualitative interviews with a purposeful sample of nurses and respiratory therapists...

BACKGROUND: Use of automated external defibrillators (AEDs) has been recommended for pediatric out-of-hospital cardiac arrest (OHCA). However, there are no conclusive studies that elucidated the effectiveness of public-access defibrillation (PAD) in children. METHODS: This was a nationwide, population-based, propensity score-matched study of pediatric OHCA in Japan from 2011 to 2012, based on data from the All-Japan Utstein Registry. We included pediatric OHCA patients (aged 1-17 years) who received bystander cardiopulmonary resuscitation...

OBJECTIVE: Out-of-hospital cardiac arrests (OHCA) in high-rise buildings experience lower survival and longer delays until paramedic arrival. Use of publicly accessible automated external defibrillators (AED) can improve survival, but "vertical" placement has not been studied. We aim to determine whether elevator-based or lobby-based AED placement results in shorter vertical distance travelled ("response distance") to OHCAs in a high-rise building. METHODS: We developed a model of a single-elevator, n-floor high-rise building...

Background Early defibrillation plays a key role in improving survival in patients with out-of-hospital cardiac arrests due to ventricular fibrillation (ventricular-fibrillation cardiac arrests), and the use of publicly accessible automated external defibrillators (AEDs) can help to reduce the time to defibrillation for such patients. However, the effect of dissemination of public-access AEDs for ventricular-fibrillation cardiac arrest at the population level has not been extensively investigated. Methods From a nationwide, prospective, population-based registry of patients with out-of-hospital cardiac arrest in Japan, we identified patients from 2005 through 2013 with bystander-witnessed ventricular-fibrillation arrests of presumed cardiac origin in whom resuscitation was attempted...

PURPOSE: Early and good quality cardiopulmonary resuscitation (CPR) and the use of automated external defibrillators (AEDs) improve cardiac arrest patients' survival. However, AED peri- and post-shock/analysis pauses may reduce CPR effectiveness. METHODS: The time performance of 12 different commercially available AEDs was tested in a manikin based scenario; then the AEDs recordings from the same tested models following the clinical use both in Pavia and Ticino were analyzed to evaluate the post-shock and post-analysis time...

BACKGROUND: The use of an automated external defibrillator (AED) prior to EMS arrival can increase 30-day survival in out-of-hospital cardiac arrest (OHCA) significantly. Drones or unmanned aerial vehicles (UAV) can fly with high velocity and potentially transport devices such as AEDs to the site of OHCAs. The aim of this explorative study was to investigate the feasibility of a drone system in decreasing response time and delivering an AED. METHODS: Data of Global Positioning System (GPS) coordinates from historical OHCA in Stockholm County was used in a model using a Geographic Information System (GIS) to find suitable placements and visualize response times for the use of an AED equipped drone...

AIM: Approximately 424,000 out-of-hospital cardiac arrests (OHCA) occur in the US annually. As automated external defibrillators (AED) are an important part of the community response to OHCA, we investigated how well the spatial demand (likelihood of OHCA) was met by the spatial supply (AEDs) in a dense urban environment. METHODS: Using geographic information system (GIS) software, we applied kernel density and optimized hot spot procedures with two differently-sized radii to model OHCA incidence rates from existing studies, providing an estimate of OHCA likelihood at a given location...

REVIEW
Sara Saberi, Sharlene M Day
Inherited cardiomyopathies have highly variable expression in terms of symptoms, functional limitations, and disease severity. Associated risk of sudden cardiac death is also variable. International guidelines currently recommend restriction of all athletes with cardiomyopathy from participation in competitive sports. While the guidelines are necessarily conservative because predictive risk factors for exercise-triggered SCD have not been clearly identified, the risk is clearly not uniform across all athletes and all sports...

BACKGROUND: The benefits of available automatic external defibrillators (AEDs) for out-of-hospital cardiac arrests (OHCAs) are well known, but strategies for their deployment outdoors remain somewhat arbitrary. Our study sought to assess different strategies for AED deployment. METHODS: All OHCAs in Paris between 2000 and 2010 were prospectively recorded and geocoded. A guidelines-based strategy of placing an AED in locations where more than one OHCA had occurred within the past five years was compared to two novel strategies: a grid-based strategy with a regular distance between AEDs and a landmark-based strategy...

The Dispatcher-Assisted first REsponder programme aims to equip the public with skills to perform hands-only cardiopulmonary resuscitation (CPR) and to use an automated external defibrillator (AED). By familiarising them with instructions given by a medical dispatcher during an out-of-hospital cardiac arrest call, they will be prepared and empowered to react in an emergency. We aim to formalise curriculum and standardise the way information is conveyed to the participants. A panel of 20 experts were chosen...

INTRODUCTION: Survival after out-of-hospital cardiac arrest (OHCA) remains low. Early recognition by emergency medical dispatchers is essential for an effective chain of actions, leading to early cardiopulmonary resuscitation, use of an automated external defibrillator and rapid dispatching of the emergency medical services. AIM: To analyse and compare the accuracy of OHCA recognition by medical dispatchers in two countries. METHOD: An observational register-based study collecting data from national cardiac arrest registers in Denmark and Sweden during a six-month period in 2013...
