Although cardiac arrest during airline flights is relatively uncommon, the unusual setting, limited resources, and the variability of the skills in medical volunteers present unique challenges. Survival in patients who suffer a witnessed arrest with a shockable rhythm who are treated promptly has improved since the advent of widely available automated external defibrillators (AEDs). In general, the chances of survival from an out-of-hospital cardiac arrest (OHCA) are greater when ventricular fibrillation (VF) is seen as the initial rhythm or if there is return of spontaneous circulation (ROSC)...

CLINICAL INTRODUCTION: A man in his early 30s with remote history of a febrile rash as a toddler presented to the emergency room following an out-of-hospital cardiac arrest while riding his bicycle. He received bystander cardiopulmonary resuscitation and one shock from an automatic external defibrillator, successfully restoring sinus rhythm. On arrival, he was haemodynamically stable without ECG evidence of ST segment changes to suggest active ischaemia, and an initial troponin I was mildly elevated at 0...

BACKGROUND: Despite the many recent improvements in basic life support (BLS) and the widespread training to a great number of lay rescuers, out-of-hospital cardiac arrest (OHCA) is still a major cause of death. Nowadays, BLS teaching protocols ask for many concepts to be learned and specific algorithms to be applied, without any available data on how much all these inputs are retained by the students. The present survey aims to evaluate how BLS is really retained by those rescuers (laypersons and nurses) who do not often put it into practice...

Pediatric cardiac arrest in the out-of-hospital setting is a traumatic event for family, friends, caregivers, classmates, and school personnel. Immediate bystander cardiopulmonary resuscitation and the use of automatic external defibrillators have been shown to improve survival in adults. There is some evidence to show improved survival in children who receive immediate bystander cardiopulmonary resuscitation. Pediatricians, in their role as advocates to improve the health of all children, are uniquely positioned to strongly encourage the training of children, parents, caregivers, school personnel, and the lay public in the provision of basic life support, including pediatric basic life support, as well as the appropriate use of automated external defibrillators...

Sudden cardiac death (SCD) in athletes is a rare but tragic complication of a number of cardiovascular diseases. Inherited causes such as the structural and arrhythmogenic genetic heart conditions are often found or suspected to be the underlying cause of death at post mortem examination. Physical activity and intense exercise may trigger cardiac arrhythmias in individuals with these conditions leading to SCD. Prevention and treatment strategies include individual athlete management strategies, coupled with public health measures such as universal cardiopulmonary resuscitation (CPR) training and availability of automatic external defibrillators (AEDs) in public places, thereby preventing SCD in both athletes and the general population...

A previously asymptomatic young female with no previous medical or cardiac history collapsed during indoor exercise. A portable automatic external defibrillator showed a shockable rhythm. She received multiple electrical shocks with return to normal sinus rhythm without ischaemic ECG changes. Her troponin level was mildly elevated. A transthoracic echocardiogram revealed moderately reduced left ventricular ejection fraction with global hypokinesis. During emergent coronary angiography, the left main coronary artery could not be found...

BACKGROUND: Mathematical optimisation models have recently been applied to identify ideal Automatic External Defibrillator (AED) locations that maximise coverage of Out of Hospital Cardiac Arrest (OHCA). However, these fixed location models cannot relocate existing AEDs in a flexible way, and have nearly exclusively been applied to urban regions. We developed a flexible location model for AEDs, compared its performance to existing fixed location and population models, and explored how these perform across urban and rural regions...

Out-of-hospital cardiac arrest (OHCA) is a leading cause of death in developed industrial countries. The global worldwide average of OHCA incidence in adults is 95.9/100,000/year. European incidences vary according to source from 16 to 119/100,000/year. The aim of this study was to provide an overview of current information on OHCA. The incidences in various populations are discussed, along with the factors affecting the prognosis and outcome of these patients. The etiology and pathophysiological mechanisms are also described, especially in relation to the most common causes - acute and chronic forms of coronary artery disease and cardiomyopathies...

In England, fewer than 1 in 10 out-of-hospital cardiac arrest victims survive to hospital discharge. This could be substantially improved by increasing bystander cardiopulmonary resuscitation and Automated External Defibrillator use. GoodSAM is a mobile-phone, app-based system alerting trained individuals to nearby cardiac arrests. 'Responders' can be notified by bystanders using the GoodSAM 'Alerter' function. In London, when a 999 call-handler identifies cardiac arrest, in addition to dispatching the usual professional resources, London Ambulance Service automatically activates nearby GoodSAM responders...

It's necessary to interrupt cardiopulmonary resuscitation (CPR) for a reliable automatic external defibrillator (AED) rhythm analysis, because the mechanical activity from the chest compressions introduces artifacts in the electrocardiogram (ECG) that substantially lower the capacity of an AED to judge cardio-electric rhythm. However, repeated interruptions of compression will reduce the quality of CPR, which in turn affect the prognosis of patients with cardiac arrest (CA). In order to improve the quality of CPR, reduce the interruptions of chest compression and implement accurate defibrillation, people have made many efforts on identifying ECG rhythm in CPR...

The increase in mortality associated with arrhythmia is an inevitable problem of modern society such as westernized eating habits and an increase in stress due to industrialization, and the related social costs are increasing. In this regard, the supply of automatic external defibrillator (AED) used outside hospitals is increasing mainly in public institutions, and AED is a medical practice performed by non-medical personnel. Therefore, studies on arrhythmia detection algorithm to make accurate clinical judgment for proper use are increasing...

Cardiac arrest is defined as the termination of cardiac activity associated with loss of consciousness, of spontaneous breathing, and of circulation. Sudden cardiac arrest and sudden cardiac death (SCD) are terms often used interchangeably. Most patients with out-of-hospital cardiac arrest have shown coronary artery disease or symptoms during the hour before the event. Cardiac arrest is potentially reversible by cardiopulmonary resuscitation, defibrillation, cardioversion, cardiac pacing, or treatments targeted at the underlying disease (e...

Poorly tolerated broad QRS complex tachycardia in a newborn poses problems with its diagnosis and emergency management. We report the case of a 35-day-old newborn with broad QRS complex tachycardia admitted because of cardiocirculatory distress. Doppler echocardiography showed morphologically normal heart. The patient received a loading dose of amiodarone but it didn't attenuate tachycardia. Normal sinus rhythm was restored after cardioversion through Lifeline semi-automatic external defibrillator. Maintenance therapy was based on oral amiodarone...

Lightning strike injuries, although less common than electrical injuries, have a higher morbidity rate because of critical alterations of the circulatory system, respiratory system, and central nervous system. Most lightning-related deaths occur immediately after injury because of arrhythmia or respiratory failure. We describe the case of a pediatric patient who experienced cardiorespiratory arrest secondary to a lightning strike, where the Advanced Cardiac Life Support and Basic Life Support chain of survival was well executed, leading to return of spontaneous circulation and intact neurological survival...

INTRODUCTION: Out of hospital cardiac arrest (OHCA) occurs frequently and the outcome is often dismal. Early defibrillation saves lives and brain function in OHCA. The Zurich city police (STAPO) forces were instructed and equipped to provide basic life support (BLS) and to use an AED in 2009. METHODS: Retrospective observational study comparing period 1 (P1) 2004-2009 before equipping and training of the STAPO and period 2 (P2) 2010-2015 after the implementation...
