BACKGROUND: Early recurrences (ERs) of atrial tachyarrhythmia are common after catheter ablation of atrial fibrillation. A 3-month blanking period is recommended by current guidelines. This study sought to investigate the significance of ER during the first 3 months post ablation in predicting late recurrences and determine whether it varies according to timing. METHODS AND RESULTS: A total of 401 patients with paroxysmal atrial fibrillation undergoing pulmonary vein isolation were followed for 12 months with transtelephonic monitoring in the ADVICE (Adenosine Following Pulmonary Vein Isolation to Target Dormant Conduction Elimination) trial...

The 2016 ESC guideline on prevention and therapy of ventricular tachyarrhythmias and sudden cardiac death present an excellent recommendation and summary for all forms of ventricular tachyarrhythmias in patients with and without structural or electrical heart disease. This includes cardiomyopathies as well as conditions such as proarrhythmia, neurologic/psychaitric disorders, or pregnancy. Some aspects are novel; (1) the guideline emphasizes for the first time genetic work-up in sudden cardiac death victims; (2) for prevention of sudden cardiac death systematic re-evaluation 6-12 weeks after myocardial infarction is recommended; (3) subcutaneous ICD as well as the wearable cardioverter/defibrillator are for the first time included in the guidelines; (4) automatic external defibrillators are recommended for public places; (5) for patients with recurrent ventricular tachyarrhythmias the role of catheter ablation has been upgraded...

In the majority of cases sudden cardiac death (SCD) is caused by ventricular tachyarrhythmia. Implantable cardioverter-defibrillators (ICD) represent an evidence-based and established method for prevention of SCD. For patients who do not fulfill the criteria for guideline-conform implantation of an ICD but still have an increased, e.g. transient risk for SCD, a wearable cardioverter-defibrillator (WCD) vest was developed to temporarily prevent SCD. Numerous studies have shown the safety and efficacy of the WCD, although there is still a gap in evidence concerning a reduction in overall mortality and improvement in prognosis...

Device therapy in the complex congenital heart disease (CHD) population is a challenging field. There is a myriad of devices available, but none designed specifically for the CHD patient group, and a scarcity of prospective studies to guide best practice. Baseline cardiac anatomy, prior surgical and interventional procedures, existing tachyarrhythmias and the requirement for future intervention all play a substantial role in decision making. For both pacing systems and implantable cardioverter defibrillators, numerous factors impact on the merits of system location (endovascular versus non-endovascular), lead positioning, device selection and device programming...

INTRODUCTION: Ventricular tachyarrhythmias (ventricular tachycardia and ventricular fibrillation) can lead to aborted cardiac arrest or sudden cardiac death in patients with poor left ventricular function early after acute myocardial infarction (AMI). Although it has been shown that the implantable cardioverter defibrillator (ICD) can treat ventricular tachyarrhythmias and save lives in patients with ischemic cardiomyopathy, it's use during the early phase post AMI has not been shown to reduce mortality...

Arrhythmogenic right ventricular cardiomyopathy (ARVC) is a genetically determined disease which predisposes to life-threatening ventricular arrhythmias. The main goal of ARVC therapy is prevention of sudden cardiac death (SCD). Implantable cardioverter defibrillator (ICD) is the most effective therapy for interruption of potentially lethal ventricular tachyarrhythmias. Despite its life-saving potential, ICD implantation is associated with a high rate of complications and significant impact on quality of life...

INTRODUCTION: Cardiopulmonary resuscitation represents a therapeutic challenge. Evidence-based guidelines, which were updated in 2015, give detailed advice on how to treat the patient. METHODS: Basic life support consists of cardiopulmonary resuscitation (30 chest compressions interrupted briefly to provide to 2 ventilations) and, if ventricular tachyarrhythmia is present, urgent cardiac defibrillation. Administration of drugs is one of the aspects of advanced life support...

AIMS: Guidelines recommend evaluation of family members of sudden cardiac death victims. However, initiation of cascade screening in families with uncertain diagnoses is not cost-effective and may cause unnecessary concern. For these reasons, we set out to assess to what extent cardiac magnetic resonance imaging (CMR) would increase the diagnostic precision and thereby possibly change the indication for family screening in patients with ventricular tachyarrhythmias. METHODS AND RESULTS: We retrospectively collected data from 79 patients hospitalized with aborted cardiac arrest (resuscitated from a cardiac arrest), ventricular tachycardia (VT), or syncope who underwent a CMR at the Copenhagen University Hospital, Rigshospitalet, Denmark...

BACKGROUND: in-hospital life-threatening ventricular arrhythmias (LT-VA) may complicate the course of cardiovascular patients. We aimed to assess the incidence, circumstances, determinants, and outcome of in-hospital LT-VA in order to help clinicians in prescribing appropriate levels of monitoring. METHODS: the study population consisted of all 10,741 consecutive patients (65 ± 15 years, 67.7% males) admitted to a cardiology department in 2009-2014. Terminally ill patients and those with primary arrhythmia diagnosis were excluded...

UNLABELLED: Heart rate is commonly used in pediatric early warning scores. Age-related changes in the anatomy and physiology of infants and children produce normal ranges for electrocardiogram features that differ from adults and vary with age. Bradycardia is defined as a heart rate below the lowest normal value for age. Pediatric bradycardia most commonly manifests as sinus bradycardia, junctional bradycardia, or atrioventricular block. As a result of several different etiologies, it may occur in an entirely structurally normal heart or in association with concomitant congenital heart disease...

BACKGROUND: In acute coronary syndrome (ACS), potassium levels <3.5 mEq/L are associated with ventricular arrhythmias. Current guidelines therefore recommend a potassium target >4.0 mEq/L in ACS. Our study evaluated the association between potassium levels, cardiac arrhythmias, and cardiovascular death in patients with non-ST-segment elevation myocardial infarction or unstable angina. METHODS: Potassium levels were measured in 6515 patients prior to randomization to receive either ranolazine or a placebo in the MERLIN-TIMI 36 trial...

BACKGROUND: Current guidelines recommend at least 24-hour Holter monitoring at 6-month intervals to evaluate the recurrence of atrial fibrillation (AF) after surgical ablation. In this prospective multicenter study, conventional intermittent methods of AF monitoring were compared with continuous monitoring using an implantable loop recorder (ILR). METHODS: From August 2011 to January 2014, 47 patients receiving surgical treatment for AF at 2 institutions had an ILR placed at the time of operation...

BACKGROUND: Current guidelines recommend the implantation of an implantable cardioverter-defibrillator (ICD) for primary prevention of sudden cardiac death (SCD) in a subgroup of patients with nonishcemic cardiomyopathy (NICM) who have a left ventricular ejection fraction (LVEF) ≤30% to 35%, and are NYHA functional class Ⅱ or Ⅲ. However, the majority of patients with an ICD implantation for primary prevention did not receive appropriate ICD therapy. The purpose of this study was to evaluate the association between myocardial fibrosis detected by cardiovascular magnetic resonance (CMR) imaging and life-threatening ventricular arrhythmic events in NICM patients...

BACKGROUND: Current guidelines recommend a 3-month blanking period after pulmonary vein isolation (PVI) as early recurrence of atrial tachyarrhythmia (ERAT) may be due to transient proarrhythmic factors. However, studies have suggested that these factors resolve by 1 month. PV reconnection (PVrc) is strongly associated with postblanking AT recurrence in paroxysmal atrial fibrillation. We hypothesized that ERAT occurring beyond 4 weeks after PVI is associated with PVrc at repeat electrophysiology study...

OBJECTIVES: Clinical guidelines recommend norepinephrine as initial vasopressor of choice for septic shock, with dopamine suggested as an alternative vasopressor in selected patients with low risk of tachyarrhythmias and absolute or relative bradycardia. We sought to determine practice patterns and outcomes associated with vasopressor selection in a large, population-based cohort of patients with septic shock that allows for assessment of outcomes in clinically important subgroups. DESIGN: We performed a retrospective cohort study to determine factors associated with choice of dopamine as compared with norepinephrine as initial vasopressor for patients with septic shock...

BACKGROUND AND AIM: The aim of this study was to evaluate the effect of statin treatment on P-wave morphology, dispersion, and tissue Doppler imaging-derived atrial conduction time (PA-TDI), which are known to be predictors of atrial fibrillation (AF). METHODS: A total of 132 patients with guideline-directed statin indications but no clinical atrial tachyarrhythmias were studied. P-wave duration, P-wave dispersion, and P-wave amplitude on surface 12-lead electrocardiogram and PA-TDI were evaluated before and after three months of statin (either atrovastatin 10-40 mg/d or rosuvastatin 10-20 mg/d) treatment...

AIMS: Hypertrophic cardiomyopathy is one of the main causes of sudden death in young people. Recent clinical practice guidelines include a risk prediction model for sudden death (HCM Risk-SCD), which facilitates the decision of whether to implant a defibrillator. The aim of our study was to ascertain the percentage of events in our series of primary prevention implantable cardioverter-defibrillator recipients with hypertrophic cardiomyopathy and whether HCM Risk-SCD predicts the onset of arrhythmic events...

Arrhythmogenic right ventricular dysplasia/cardiomyopathy (ARVD/C) is an inherited genetic disease caused by defective desmosomal proteins, and it has typical histopathological features characterized by predominantly progressive fibro-fatty infiltration of the right ventricle. Clinical presentations of ARVD/C vary from syncope, progressive heart failure (HF), ventricular tachyarrhythmias, and sudden cardiac death (SCD). The 2010 modified Task Force criteria were established to facilitate the recognition and diagnosis of ARVD/C...

Sinus node disease (SND), a common indication to implant a pacemaker, is frequently associated with atrial fibrillation (AF), either at implantation (paroxysmal AF) or during follow-up, which often evolves to persistent or permanent AF. Pacemakers with an atrial lead allow continuous monitoring of the atrial rhythm and enable detection of the burden of AF. Asymptomatic atrial tachyarrhythmias, being associated with increased risk of stroke, have important prognostic implications, and their detection could guide decision-making about antithrombotic prophylaxis...
