BACKGROUND: Patients on mechanical ventilation are at risk of experiencing a potentially life-threatening unplanned extubation in the intensive care unit, which can lead to arrhythmias, bronchial aspiration, difficulty in reintubation or even sudden cardiac arrest. Although incidence and outcomes of the phenomenon have been documented in several quantitative studies, no studies have investigated the antecedents as experienced by critical care nurses. OBJECTIVES: To gain a greater understanding of the antecedents of unplanned extubations...

BACKGROUND: The implantable cardioverter defibrillator provides effective treatment for the prevention of sudden cardiac arrest but significant risks associated with transvenous implantation persist. The subcutaneous implantable cardioverter defibrillator has proven to be an alternative and innovative treatment option for select patients to mitigate these risks. Obtaining the patients' perspectives can provide clinicians with essential information to guide implant selection, procedural decision-making, and support patient management...

BACKGROUND: Right ventricular systolic dysfunction (RVD) often coexists with various cardiopulmonary diseases. However, the association between RVD and risk of sudden cardiac death (SCD) has not been well studied. This study examined the risk of SCD associated with RVD in patients with heterogeneous underlying cardiac diseases. METHODS: The Mayo Clinic cardiac care unit database included 5463 consecutive patients with complete echocardiographic evaluation to assess right ventricular systolic function and RVD severity...

RATIONALE: Critical care ultrasound identifies the signs of free intraperitoneal air and echogenic free fluid always indicates hollow viscus perforation (HVP) and needs immediate surgical interventions. However, in rare cases, these classic signs may also mislead proper clinical decisions. We report perforated viscus associated large peritoneal effusion with initial critical care ultrasound findings, whereas computed tomography (CT) examination confirmed a giant stomach due to superior mesenteric artery syndrome (SMAS)...

BACKGROUND: Limited information exists about detailed clinical characteristics and management of the small subset of Brugada syndrome (BrS) patients who had an arrhythmic event (AE). OBJECTIVES: To conduct the first nationwide survey focused on BrS patients with documented AE. METHODS: Israeli electrophysiology units participated if they had treated BrS patients who had cardiac arrest (CA) (lethal/aborted; group 1) or experienced appropriate therapy for tachyarrhythmias after prophylactic implantable cardioverter defibrillator (ICD) implantation (group 2)...

OBJECTIVES: This study evaluated the yield of ajmaline testing and assessed the occurrence of confounding responses in a large cohort of families with unexplained cardiac arrest (UCA) or sudden unexplained death (SUD). BACKGROUND: Ajmaline testing to diagnose Brugada syndrome (BrS) is routinely used in the evaluation of SUD and UCA, but its yield, limitations, and appropriate dosing have not been studied in a large cohort. METHODS: We assessed ajmaline test response and genetic testing results in 637 individuals from 482 families who underwent ajmaline testing for SUD or UCA...

Brugada syndrome (BrS) is an inherited cardiac arrhythmia syndrome characterized by ST-segment elevation in right precordial ECG leads and associated with sudden cardiac death in young adults. The ECG manifestations of BrS are often concealed but can be unmasked by sodium channel blockers and fever. Areas covered: Implantation of a cardioverter defibrillator (ICD) is first-line therapy for BrS patients presenting with prior cardiac arrest or documented VT. A pharmacological approach to therapy is recommended in cases of electrical storm, as an adjunct to ICD and as preventative therapy...

BACKGROUND: Heterologous functional validation studies of putative long-QT syndrome subtype 2-associated variants clarify their pathological potential and identify disease mechanism(s) for most variants studied. The purpose of this study is to clarify the pathological potential for rare nonsynonymous KCNH2 variants seemingly associated with sudden infant death syndrome. METHODS: Genetic testing of 292 sudden infant death syndrome cases identified 9 KCNH2 variants: E90K, R181Q, A190T, G294V, R791W, P967L, R1005W, R1047L, and Q1068R...

The purpose of the study is to examine (1) nationally representative incidence rates of Emergency Department (ED) visits due to sudden cardiac arrest (SCA) in pediatric and young adult populations, (2) basic characteristics of the ED visits with SCA, and (3) patient and hospital factors associated with survival after SCA. We used the Nationwide Emergency Department Sample from 2006 to 2013. ICD-9-CM diagnostic codes identified ED visits due to SCA for patients ≤ 30 years old. Outcomes included yearly incidence of ED visits for SCA, and survival to hospital discharge...

BACKGROUND: Little is known about the association between provision of post-resuscitation care and prognosis of out-of-hospital cardiac arrest(OHCA) in elderly patients. Previous studies have suggested futility after 65 years of age. OBJECTIVES: We aimed to evaluate the association of early coronary angiogram(CAG) followed if necessary by percutaneous coronary intervention(PCI), with favorable outcome after OHCA among elderly patients, compared to younger patients...

Laith Cebe, Harpreet Singh
Reflex anoxic seizures (RAS) are essential in the differential diagnosis of non-epileptic paroxysmal seizures. They are precipitated by vagally mediated brief cardiac asystole, which in turn leads to transient cerebral ischaemia. RAS are usually seen in infants and preschool children, but in this case happened in a middle-aged man. Our patient is a 61-year-old man who presented with sudden, repeated contractions of his left upper arm and urine incontinence, followed by loss of consciousness for about 30 s...

Prashant Rao, Karl Kern
Out-of-Hospital Cardiac Arrest affects 350,000 Americans each year. Unfortunately, the national survival rate from such an event remains no better than 12% [1], though some communities do better and some worse [2]. The "Chain of Survival" concept has been accepted for decades and remains the roadmap for many communities in their efforts to improve their local survival rates from sudden cardiac death (SCD) (3-Chain of Survival concept). The key for this chain to be successful is the EARLY application of each link in the sequence of treating cardiac arrest...

Puneet K Aulakh, David E Westerman, Raj C Dedhia
Autonomic dysfunction (AD) has been associated with both obstructive and central sleep apneas. Several mechanisms have been proposed for the emergence of sleep apnea in AD, which include impaired sensory input, compromised local reflexes, and altered central processing. We present a case of a 70-year-old woman who had experienced cardiac arrest four times related to hypoxic events due to the apparent sudden onset of obstructive sleep apnea (OSA) in the setting of AD. The episodes of OSA were profoundly prolonged and a tracheostomy was ultimately needed due to the inability of positive airway pressure therapy with supplemental oxygen to control events...

BACKGROUND AND PURPOSE: Oxycodone is a potent semi-synthetic opioid that is commonly used for the treatment of severe acute and chronic pain. However, treatment with oxycodone can lead to cardiac electrical changes, such as long-QT syndrome, potentially inducing sudden cardiac arrest. Here, we investigate whether the cardiac side effects of oxycodone can be explained by modulation of the cardiac sodium channel Nav1.5. EXPERIMENTAL APPROACH: Heterologously expressed Nav1...

The evidence to support implantable cardioverter defibrillator (ICD) in subjects with nonischemic cardiomyopathy (NICM) for primary prevention of sudden cardiac death (SCD) is not robust. This meta-analysis intends to assess the impact of routine ICD implantation for primary prevention of mortality due to SCD in NICM based on all the published randomized clinical trials (RCTs). Six RCTs were selected using PubMed/Medline, EMBASE, and CENTRAL from inception to December 2016. Outcomes were calculated as random-effects relative risk (RR) and risk difference (RD) with 95% confidence interval (CI)...

Despite the cardiovascular benefits of regular sports, sudden cardiac arrest (SCA) risk is increased during or shortly after exercise. Association with coronary artery disease (CAD) has been described in small studies, mainly autopsic with potential bias given the high sports-related SCA survival, and focusing on young competitive athletes, whereas sports-related SCA occurs mostly in recreational athletes.1-5 Through the Paris Sudden Death Expertise Center prospective registry that includes all SCAs in Paris and suburbs since May 2011, we performed the first broad comprehensive CAD description in sports-related SCAs, with a comparison with matched non-sports-related SCAs...
