BACKGROUND: Population based studies showed an association of early repolarization in the electrocardiogram (ECG) and a higher rate of sudden cardiac death presumably due to ventricular fibrillation. The triggers for ventricular fibrillation in patients with early repolarization are not fully understood. CASE PRESENTATION: We describe the case of a young patient with a survived ventricular fibrillation arrest while asleep followed by multiple episodes of recurrent ventricular fibrillation...

BACKGROUND: The incidence of sudden cardiac arrest during participation in sports activities remains unknown. Preparticipation screening programs aimed at preventing sudden cardiac arrest during sports activities are thought to be able to identify at-risk athletes; however, the efficacy of these programs remains controversial. We sought to identify all sudden cardiac arrests that occurred during participation in sports activities within a specific region of Canada and to determine their causes...

Sudden death is defined as unexpected cardiac arrest occurring less than one hour after the onset of the first symptoms. Between 2010 and 2012, 23 maternal deaths were considered as unexplained sudden deaths and three of them were not evaluated due to a lack of clinical data. In addition, 13 maternal deaths with an identified cause occurred in a clinical context of sudden death (7 cases of pulmonary embolism, 2 cases of epilepsy, and 2 cases of cardiomyopathy). The first maneuvers of resuscitation in the presence of bystanders were attempted in 8 of 22 cases (36%)...

Case: Thrombocytopenia, anasarca, fever, renal insufficiency, and organomegaly (TAFRO) syndrome is a newly defined systemic inflammatory disorder with gradual progression of symptoms. A 59-year-old man with fever and ascites of unknown cause developed sudden-onset shock and respiratory failure in the general ward. Cardiac arrest immediately followed. Although he was resuscitated, frequent administration of adrenaline was required to maintain his blood pressure. His circulation was most effectively stabilized by drainage of fluid from his distended abdomen...

Gordon A Ewy
Sudden cardiac arrest is a major public health problem in the industrialized nations of the world. Yet, in spite of recurrent updates of the guidelines for cardiopulmonary resuscitation and emergency cardiac care, many areas have suboptimal survival rates. Cardiocerebral resuscitation, a non-guidelines approach to therapy of primary cardiac arrest based on our animal research, was instituted in Tucson (AZ, USA) in 2002 and subsequently adopted in other areas of the USA. Survival rates of patients with primary cardiac arrest and a shockable rhythm significantly improved wherever it was adopted...

Objective: To establish which risk factors are predictive for sudden death in hypertrophic cardiomyopathy (HCM) diagnosed in childhood. Methods: A Swedish national cohort of patients with HCM diagnosed <19 years of age was collected between 1972 and 2014, consisting of 155 patients with available ECGs, with average follow-up of 10.9±(SD 9.0) years, out of whom 32 had suffered sudden death or cardiac arrest (SD/CA group). Previously proposed risk factors and clinical features, ECG and ultrasound measures were compared between SD/CA group and patients surviving >2 years (n=100), and features significantly more common in SD/CA group were further analysed with univariate and multivariate Cox hazard regression in the total cohort...

Cardiopulmonary resuscitation is a lifesaving technique for victims of sudden cardiac arrest. Despite advances in resuscitation science, basic life support remains a critical factor in determining outcomes. The American Heart Association recommendations for adult basic life support incorporate the most recently published evidence and serve as the basis for education and training for laypeople and healthcare providers who perform cardiopulmonary resuscitation.

C Spaulding, N Karam
Out-of-hospital cardiac arrest is most often due to an acute coronary artery occlusion. The cause of coronary thrombosis in cardiac arrest is debated. Plaque erosion could be a trigger leading to immediate thrombus formation followed by ventricular fibrillation or rapid ventricular tachycardia. Coronary artery spasm is frequent: spasm provocation tests should be performed in survivors with normal coronary arteries. Use of drugs such as cocaine can lead to sudden death and blood sampling at arrival is recommended in survivors of out-of-hospital cardiac arrest...

Patients with a Brugada type 1 electrocardiogram (ECG) pattern may suffer sudden cardiac death (SCD). Recognized risk factors are spontaneous type 1 ECG and syncope of presumed arrhythmic origin. Familial sudden cardiac death (f-SCD) is not a recognized independent risk factor. Finally, positive electrophysiologic study (+EPS) has a controversial prognostic value. Current ESC guidelines recommend implantable cardioverter defibrillator (ICD) implantation in patients with a Brugada type 1 ECG pattern if they have suffered a previous resuscitated cardiac arrest (class I recommendation) or if they have syncope of presumed cardiac origin (class IIa recommendation)...

Keeping children safe is a goal for everyone. To stay safe, some children need a wearable cardioverter defibrillator (WCD). WCDs protect individuals who are at risk for life-threatening arrhythmias. The LifeVest(®) (ZOLL, Pittsburgh, PA) is a WCD that identifies, records, and treats potentially life-threatening abnormal heartbeats, or arrhythmias. The WCD will provide electrical energy to the heart with up to five high energy shocks if a potentially dangerous cardiac arrhythmia is detected. This type of arrhythmia, if not treated within a short time period (less than 2 minutes), can result in disruption of blood flow to the brain and other vital organs (that is, a sudden cardiac arrest), and death can occur within minutes...

BACKGROUND: Beta-blockers are first-line therapy in patients with congenital long-QT syndrome (LQTS). OBJECTIVE: This study sought to determine the differences in effectiveness of beta-blockers on risk reduction according to LQTS genotype. METHODS: We searched MEDLINE, EMBASE, and CENTRAL databases to investigate the use of beta-blockers (atenolol, nadolol, propranolol, and metoprolol) in patients with LQTS. Hazard ratio (HR) and relative risk (RR) were extracted or calculated from studies reporting cardiac events (syncope, aborted cardiac arrest (ACA), or sudden cardiac death (SCD))...

BACKGROUND AND PURPOSE: The early diagnosis of LMNA-associated muscular dystrophy is important for preventing sudden arrest related to cardiac conduction block. However, diagnosing early-onset Emery-Dreifuss muscular dystrophy (EDMD) with later involvement of contracture and limb-girdle muscular dystrophy type 1B is often delayed due to heterogeneous clinical presentations. We aimed to determine the clinical features that contribute to a delayed diagnosis. METHODS: We reviewed four patients who were recently diagnosed with LMNA-associated muscular dystrophy by targeted exome sequencing and who were initially diagnosed with nonspecific or other types of muscular dystrophy...

In the present review, we summarize current approaches to the prevention of sudden cardiac death (SCD) in children and young adults, focusing on age less than 35 years. SCD in the young is rare, but devastating from the societal perspective. While coronary artery disease is the main etiology of SCD in the older age groups, conditions such as cardiomyopathies and electrical channelopathies are more likely to be found in the young. In the majority of younger cases, cardiac arrest can be the first recognized manifestation of the underlying cardiac pathology, although some have experienced cardiovascular symptoms prior to the SCD...

A 65-year-old man with history of aortobifemoral surgery 4 years ago was admitted to hospital after sudden abdominal pain. Initially misdiagnosed as renal colic, he was treated with analgesics, and while on observation he started with haematemesis, rapidly responding to volume infusion. Upper gastrointestinal endoscopy showed fresh blood in the stomach with no visible active bleeding. CT scan showed an important contrast extravasation from the aorta to the third duodenal portion, restarting haemodynamic instability and a cardiac arrest...
