BACKGROUND: A proportion of patients who receive cardiac resynchronization therapy (CRT) with defibrillator (CRT-D) live to receive a second generator. Controversy exists on whether an implantable cardioverter-defibrillator (ICD) should be offered to patients who have normalized or near normalized left ventricular ejection fraction (LVEF) at the time of generator replacement (GR). OBJECTIVE: To evaluate incidence of appropriate ICD therapy after CRT-D GR. METHODS: This series involved 1,026 consecutive patients who underwent CRT-D implant between January 2002 and December 2012...

The current regulatory guidelines recommend the use of QT interval to assess the risk of arrhythmogenic potential of new chemical entities. Recently, the electromechanical window (EMW), the difference in duration between electrical and mechanical systole, has been proposed as markers for drug-induced torsades de pointes (TdP); however, data of EMW in short QT model are not available. This study aimed to characterize the EMW as a marker for drug-induced ventricular arrhythmias in anesthetized rabbit model of long QT syndrome type 2 (LQT2) and short QT syndrome (SQTS) infused with reference compounds known to lengthen or shorten QT intervals...

BACKGROUND: Thyroid storm (TS) is life threatening. In the mid-2000s, its incidence was poorly defined, peer-reviewed diagnostic criteria were not available, and management and treatment did not seem to be verified based upon evidence and latest advances in medicine. METHODS: We first developed diagnostic criteria based on 99 patients in the literature and our 7 patients. We then conducted initial and follow-up surveys from 2004 through 2008, targeting all hospitals in Japan to obtain and verify information on patients who met diagnostic criteria for TS...

Although sudden cardiac death (SCD) is one of the most important modes of death in Western countries, pathologists and public health physicians have not given this problem the attention it deserves. New methods of preventing potentially fatal arrhythmias have been developed and the accurate diagnosis of the causes of SCD is now of particular importance. Pathologists are responsible for determining the precise cause and mechanism of sudden death but there is still considerable variation in the way in which they approach this increasingly complex task...

BACKGROUND: Published studies state that adherence to regular laboratory assessments for anti-arrhythmic drugs is as low as 20%. Monitoring adherence is important as other studies have shown that up to 93% of patients on amiodarone experience an adverse drug event leading to a potentially lethal event. OBJECTIVE: To determine whether patients prescribed amiodarone or dofetilide are being monitored according to package labeling and guideline recommendations for adverse events...

Sudden infant death syndrome (SIDS) is the leading cause of post-neonatal infant mortality in developed countries, characterized by the death of infants for no obvious reason and without prior warning. The complex interaction of multiple factors in the pathogenesis of SIDS is illustrated by the 'triple risk hypothesis', which proposed that SIDS results from a convergence of three overlapping risk factors: a critical developmental period, an exogenous stressor, and underlying genetic and/or nongenetic vulnerability in the infant...

BACKGROUND: The main causes of mortality in patients with chronic heart failure include sudden cardiac death (SCD) and progressive heart failure. Autonomic dysfunction plays a detrimental role in the progression of chronic heart failure. Left cardiac sympathetic denervation (LCSD) is an inexpensive and safe procedure which modifies autonomic innervation of the heart and is associated with a significant antifibrillatory effect. Whether LCSD reduces the risk of SCD, delays progression of heart failure and improves quality of life in patients with heart failure with reduced ejection fraction (HFrEF) is not known...

AIMS: Acute myocarditis is a potentially lethal inflammatory heart disease that frequently precedes the development of dilated cardiomyopathy and subsequent heart failure. At present, there is no effective standardized therapy for acute myocarditis, besides the optimal care of heart failure and arrhythmias in accordance with evidence-based guidelines and specific etiology-driven therapy for infectious myocarditis. Carvedilol has been shown to be cardioprotective by reducing cardiac pro-inflammatory cytokines present in oxidative stress in certain heart diseases...

Caffeinated energy drinks (EDs) are increasingly popular among adolescents despite growing evidence of their negative health effects. The consumption of EDs has seen a substantial increase during the past few decades, especially in the Western and Asian countries. EDs contain high levels of caffeine, sugar, and novel ingredients, and are often marketed through youth-oriented media and venues. The known and unknown pharmacology of the constituents of EDs poses a risk of caffeine toxicity and other ill effects when consumed by young people...

BACKGROUND: Although there is clear evidence to demonstrate that primary prevention implantable defibrillators (ICDs) reduce mortality in high-risk patients, ICDs are underutilized. Limited data exist assessing referring physicians' knowledge about guideline indications and attitudes towards ICDs, which may influence decision for referral. METHODS AND RESULTS: The Arrhythmia Working Group from the Alberta Cardiovascular and Stroke Strategic Clinical Network developed a web-based survey consisting of case scenarios regarding primary prevention ICD indications and a list of barriers for referral to aid in the design of a complex device care pathway...

BACKGROUND: Catheter ablation (CA) therapy is the first choice treatment in adults with heart rhythm disturbances. The arrhythmias in adults are mainly conditioned by coronary disease. Etiology of arrhythmias in children is mostly associated with inherited heart disorders. According to the current guidelines the CA is widely used in children, indicating the need to make it more achievable in pediatric population. AIM: To assess efficacy and safety of CA in children with different types of arrhythmias on the initial learning curve at newly built Ablation Center in The Independent Pediatric Hospital of Medical University of Warsaw...

INTRODUCTION: Atrial fibrillation (AF) is the most prevalent cardiac arrhythmia and causes patients considerable burden; symptoms such as palpitations and dyspnoea are common, leading to frequent emergency room visits. Patients with AF report reduced health-related quality of life (HQOL) compared with the general population; thus, treatments focus on the restoration of sinus rhythm to improve symptoms. Catheter ablation (CA) is a primary treatment strategy to treat AF-related burden in select patient populations; however, repeat procedures are often needed, there is a risk of major complications and the procedure is quite costly in comparison to medical therapy...

INTRODUCTION    Restoring sinus rhythm in patients with atrial fibrillation (AF)/atrial flutter (AFl) requires adequate oral anticoagulation prior to direct current cardioversion (DCC). Some patients eligible for DCC are not properly anticoagulated. OBJECTIVES    The aim of the study was to assess risk factors for thrombus and spontaneous echo contrast (SEC) in the left atrium (LA) as well as the safety profile of transesophageal echocardiography (TEE)-guided DCC in patients with inadequate anticoagulation...

In healthy mammalian hearts the action potential (AP) waveform initiates and modulates each contraction, or heartbeat. As a result, action potential height and duration are key physiological variables. In addition, rate-dependent changes in ventricular action potential duration (APD), and variations in APD at a fixed heart rate, are both reliable biomarkers of electrophysiological stability. Present guidelines for the likelihood that candidate drugs will increase arrhythmias rely on small changes in APD and Q-T intervals as criteria for Safety Pharmacology decisions...

BACKGROUND: Atrial fibrillation (AF) is a common arrhythmia that causes numerous visits to emergency departments (ED). The aim of the FinFib2 study was to evaluate whether treatment of patients with AF in ED is consistent with the contemporary European Society of Cardiology (ESC) management guidelines. Here we report the results of antiarrhythmic drug therapy (AAD) in ED. METHODS: All patients within the two-week study period whose primary reason for the ED visit was symptomatic AF were included into this prospective multicentre study...

Atrial fibrillation (AF) is the most common sustained arrhythmia, causing a 2-fold increase in mortality and a 5-fold increase in stroke. The Asian population is rapidly aging, and in 2050, the estimated population with AF will reach 72 million, of whom 2.9 million may suffer from AF-associated stroke. Therefore, stroke prevention in AF is an urgent issue in Asia. Many innovative advances in the management of AF-associated stroke have emerged recently, including new scoring systems for predicting stroke and bleeding risks, the development of non-vitamin K antagonist oral anticoagulants (NOACs), knowledge of their special benefits in Asians, and new techniques...

RATIONALE: Vasopressors such as norepinephrine are first line for support of mean arterial pressure (MAP) in the management of septic shock. Their use, however, is commonly associated with many adverse events. These detriments frequently trigger the use of alternative, noncatecholamine therapies, including vasopressin. Vasopressin deficiency is a known physiologic consequence of septic shock, and while guidelines recommend vasopressin in addition to norepinephrine, no consensus exists on the duration of deficiency or ideal time of cessation...
