Training in the modern form of cardiopulmonary resuscitation (CPR) started in Singapore in 1983. For the first 15 years, the expansion of training programmes was mainly owing to the interest of a few individuals. Public training in the skill was minimal. In an area of medical care where the greatest opportunity for benefit lies in employing core resuscitation skills in the prehospital environment, very little was being done to address such a need. In 1998, a group of physicians, working together with the Ministry of Health, set up the National Resuscitation Council (NRC)...

The most common initial rhythm in a sudden cardiac arrest is ventricular fibrillation or pulseless ventricular tachycardia. This is potentially treatable with defibrillation, especially if provided early. However, any delay in defibrillation will result in a decline in survival. Defibrillation requires coordination with the cardiopulmonary resuscitation component for effective resuscitation. These two components, which form the key links in the chain of survival, have to be brought to the cardiac victim in a timely fashion...

OBJECTIVE: We hypothesized that major psychological stress can be a risk factor for cardiac arrest and that effects are modified by elapsed time from specific stressful events. METHODS: Case-control study was conducted using database for cardiac arrest and emergency department (ED) visiting. Cases included adult patients with cardiac arrest with presumed cardiac etiology. Controls were matched with sex and age and visiting day from unintentional injured patients in same ED...

BACKGROUND: Although both recorded lectures and serious games have been used to pretrain health professionals before simulation training on cardiopulmonary resuscitation, they have never been compared. OBJECTIVE: The aim of this study was to compare an online course and a serious game for pretraining medical students before simulation-based mastery learning on the management of sudden cardiac arrest. DESIGN: A randomised controlled trial. Participants were pretrained using the online course or the serious game on day 1 and day 7...

BACKGROUND: Long QT syndrome (LQTS) is a potentially lethal cardiac channelopathy with a 1% to 5% annual risk of LQTS-triggered syncope, aborted cardiac arrest, or sudden cardiac death. OBJECTIVES: This study sought to evaluate LQTS outcomes from a single center in the contemporary era. METHODS: The authors conducted a retrospective study comprising the 606 patients with LQTS (LQT1 in 47%, LQT2 in 34%, and LQT3 in 9%) who were evaluated in Mayo Clinic's Genetic Heart Rhythm Clinic from January 1999 to December 2015...

BACKGROUND: Diabetes is independently associated with increased risk of sudden cardiac arrest (SCA), with a need to identify novel methods for risk stratification. Diabetics can develop autonomic dysfunction which has been associated with increased risk of ventricular arrhythmogenesis, and manifests as reduced heart rate variability (HRV). However, previously published studies have not accounted for resting heart rate (HR), important from both pathophysiologic and prognosticating standpoints...

Objective Hypertrophic cardiomyopathy (HCM) is associated with a risk of sudden cardiac death (SCD). Several models have been developed to estimate SCD risk and guide preventive therapy. The comparison of the previous 2003 with novel 2014 SCD risk models have never been studied. Methods Over a year we included 103 consecutive HCM patients without previous cardiac arrest and/or ICD implanted (65% males; aged 53.3 ± 13.9 years; mean EF 62.3 ± 18%). The SCD risk was calculated for each patient. Results Based on the 2003 model, patients had following scores: 0 points -15 (15%) patients, 1-28 (27%), 2-34 (33%), 3-18 (17%), ≥ 4-8 (8%)...

Predictive genetic testing in minors should be considered when clinical intervention is available. Children who carry a pathogenic variant for an inherited arrhythmia or cardiomyopathy require regular cardiac screening and may be prescribed medication and/or be told to modify their physical activity. Medical genetics and pediatric cardiology charts were reviewed to identify factors associated with uptake of genetic testing and cardiac evaluation for children at risk for long QT syndrome, hypertrophic cardiomyopathy or arrhythmogenic right ventricular cardiomyopathy...

Results from the DANISH Study (Danish Study to Assess the Efficacy of ICDs in Patients With Non-Ischemic Systolic Heat Failure on Mortality) suggest that for many patients with dilated cardiomyopathy (DCM), implantable cardioverter-defibrillators do not increase longevity. Accurate identification of patients who are more likely to die of an arrhythmia and less likely to die of other causes is required to ensure improvement in outcomes and wise use of resources. Until now, left ventricular ejection fraction has been used as a key criterion for selecting patients with DCM for an implantable cardioverter-defibrillator for primary prevention purposes...

BACKGROUND PRKAG2 syndrome diagnosis is already well-defined as Wolff-Parkinson-White syndrome (WPW), ventricular hypertrophy (VH) due to glycogen accumulation, and conduction system disease (CSD). Because of its rarity, there is a lack of literature focused on the treatment. The present study aimed to describe appropriate strategies for the treatment of affected family members with PRKAG2 syndrome with a long follow-up period. CASE REPORT We studied 60 selected individuals from 84 family members (32 males, 53...

INTRODUCTION: Our study looked at out-of-hospital sudden cardiac arrest events in the City of Toronto. These are relatively rare events, yet present a serious global clinical and public health problem. We report on the application of spatial methods and tools that, although relatively well known to geographers and natural resource scientists, need to become better known and used more frequently by health care researchers. MATERIALS AND METHODS: Our data came from the population-based Rescu Epistry cardiac arrest database...

Central venous catheters are a commonly used medical device which may sometimes cause complications. We present first case who had an asystolic cardiac arrest during insertion of a central venous catheter, needed cardiopulmonary resuscitation (CPR), and was resuscitated successfully. A46-year lady presented to the emergency department due to mushroom poisoning. Acentral venous catheter was inserted through the internal jugular vein. However, the patient suddenly lost consciousness and asystole was seen on the monitor immediately after the insertion of the catheter...

A 56-year-old woman presented with acute onset of typical chest pain. She was diagnosed with acute coronary syndrome with ST-segment elevation myocardial infarction. Although significant obstructive coronary artery disease was ruled out by coronary angiography, cardiac MRI showed transmural necrosis of the lateral free wall with extensive microvascular obstruction consistent with ischaemic heart disease. Within 48 hours after initial presentation, the patient suddenly arrested due to pulseless electrical activity with futile resuscitation efforts...

BACKGROUND: Sudden cardiac arrest (SCA) is a complex multifactorial event and most commonly caused by ventricular tachycardia/ fibrillation (VT/ VF). Some antihypertensive drugs could induce hypokalaemia or hyperkalaemia that may increase susceptibility to VT/VF and SCA. OBJECTIVE: To assess the association between different classes of antihypertensive drugs classified according to their potential impact on serum potassium levels and the occurrence of out-of-hospital cardiac arrest (OHCA) based on VT/VF...

BACKGROUND: Health insurance has many benefits including improved financial security, greater access to preventive care, and better self-perceived health. However, the influence of health insurance on major health outcomes is unclear. Sudden cardiac arrest prevention represents one of the major potential benefits from health insurance, given the large impact of sudden cardiac arrest on premature death and its potential sensitivity to preventive care. METHODS AND RESULTS: We conducted a pre-post study with control group examining out-of-hospital cardiac arrest (OHCA) among adult residents of Multnomah County, Oregon (2015 adult population 636 000)...

Caffeine is not usually perceived as a drug by most people because it is found in many foods and drinks, including caffeinated energy drinks, as well as in over the counter analgesics and cold preparations. Recently in Poland it has become increasingly common to take pure caffeine, bought through online stores, as a psychoanaleptic. This creates a much higher risk of severe and even fatal poisoning in comparison with the risk associated with the abuse of food products and non-prescription medicines containing low doses of caffeine...

Julie A Brothers
Anomalous aortic origin of a coronary artery (AAOCA) occurs when both coronary arteries arise from the same aortic sinus from a single ostium or two separate ostia. While most coronary anomalies are benign, the two most common subtypes that predispose to sudden cardiac death in the young are interarterial anomalous right coronary artery and interarterial anomalous left coronary artery. Practitioners face many challenges with AAOCA. Diagnosing patients may be difficult because children and adolescents are often asymptomatic and first presentation may be sudden death or sudden cardiac arrest...

Silvana Molossi, Hitesh Agrawal
Coronary artery anomalies, particularly anomalous aortic origin of a coronary artery with an interarterial course, are associated with sudden cardiac arrest or death in the young. There is paucity of data on risk stratification and longitudinal follow up is lacking in these patients. Collaboration and sharing of data among specialized centers might shed much needed light in this complex problem.
