Electrical storm during the acute inflammatory phase caused by myocarditis may be resistant to antiarrhythmic therapy. Cardiac imaging including magnetic resonance tomography, positron emission tomography, and endomyocardial biopsy are crucial to guide potential therapeutic options. Optimal management involves a multidisciplinary approach, including expertise beyond cardiology.

INTRODUCTION: Mechanism of a regular, monomorphic Wide QRS Complex Tachycardia (WCT) is an important diagnostic challenge in day to day practice for the clinicians and affects further management and prognosis. Many of the WCT and Narrow Complex Tachycardia (NCT) produce certain characteristic changes in lead aVR by which we can differentiate between them. AIM: The present study was aimed to evaluate tachyarrhythmias in relation to lead aVR and to highlight the clinical significance of lead aVR, "The Neglected Lead"...

Severe ventricular arrhythmias are frequent during heart failure; they are a life-threatening condition due to the increased risk of sudden death. Efficient management remains limited in sub-Saharan Africa because of the limited or unavailable medical resources as automated implantable defibrillator (AID). We report the case of a 56-year old patient with non ischemic dilated cardiomyopathy with very low left ventricular ejection fraction (LVEF)who underwent AID implantation for primary prevention of sudden cardiac death due to ventricular arrhythmias in 2012...

PURPOSE OF REVIEW: In this chapter we will discuss the most recent and relevant evidences published in the field of inherited arrhythmogenic disorders, focusing on the so called 'channelopathies' that are associated with sudden cardiac death (SCD) in children: long QT syndrome (LQTS), short QT syndrome (SQTS), Brugada syndrome (BrS), and catecholaminergic polymorphic ventricular tachycardia (CPVT). RECENT FINDINGS: We will discuss the latest diagnostic criteria for channelopathies released by the European Society of Cardiology, the new data on BrS in children and the recent evidence supporting a genotype-specific therapy for LQTS type 3...

BACKGROUND: Experience with percutaneous epicardial ablation of tachyarrhythmia in pediatrics is limited. This case series addresses the feasibility, safety and complications of the procedure in children. METHODS: A total of 9 patients underwent 10 epicardial ablation procedures from 2002 to 2013 at two academic centers. Activation mapping was performed in all cases, and electro-anatomic map was utilized in 9 of the 10 procedures. Patients had undergone 1-3 failed endocardial catheter ablations in addition to medical management, and all had symptoms, a high-risk accessory pathway (AP), aborted cardiac arrest with Wolff-Parkinson-White syndrome (WPW) or ventricular dysfunction...

BACKGROUND: Despite improvements in identifying high-risk patients with non-ST segment ACS (acute coronary syndrome), low risk patients presenting with atypical chest pain and non-diagnostic Electrocardiogram (ECG) continued to undergo unnecessary admissions and testing. Since 1992, our chest pain protocol included using 4-hour serial biomarkers from ED admission in combination with stress testing to evaluate these patients. Our study aimed at determining whether a new accelerated diagnostic protocol using sensitive cardiac troponin I (cTnI) 2 hours after admission to the ED followed by stress testing is safe and effective in emergency settings, allowing for appropriate triage, earlier discharge and reducing costs...

INTRODUCTION: Epicardial ablation is becoming an important part of management in patients with ventricular tachycardia (VT). Posterior epicardial access via the Sosa or Needle-in-Needle (NIN) approach for epicardial VT ablation is considered to be the method of choice for most electrophysiologists. Anterior epicardial access as an alternative technique has recently been proposed, but there is limited data about its safety, efficacy and the rate of immediate complications. In this study, we report our experience with anterior epicardial access between 2009 and 2016...

BACKGROUND: The goal was to test the effectiveness of a structured pain management programme after invasive electrophysiological interventions in cardiology including ablation of atrial fibrillation (AF) or ventricular tachycardia (VT) and implantation, or explantation, of pacemakers or implantable cardioverter defibrillators. METHODS: This was a prospective study with a pre-/post-design where a post-intervention group (116 consecutive patients) was compared to a pre-intervention group (102 consecutive patients) after implementation of a structured pain-management programme using the numeric rating scale (NRS 0-10) and classified as moderate-to-severe if NRS > 3...

INTRODUCTION: Hypergravitational exposures during human centrifugation are known to provoke dysrhythmias, including sinus dysrhythmias/tachycardias, premature atrial/ventricular contractions, and even atrial fibrillations or flutter patterns. However, events are generally short-lived and resolve rapidly after cessation of acceleration. This case report describes a prolonged ectopic ventricular rhythm in response to high G exposure. CASE REPORT: A previously healthy 30-yr-old man voluntarily participated in centrifuge trials as a part of a larger study, experiencing a total of 7 centrifuge runs over 48 h...

BACKGROUND: In Bangladesh, each emergency physician faces amitriptyline overdose nearly a day. An acute cardiovascular complication, one of the worst complications is mainly responsible for the mortality in tricyclic overdose. Recently, we managed ventricular tachycardia in a young female presented with an impaired consciousness 10 h after intentionally ingesting 2500 mg amitriptyline. Here, we report it, discuss how the electrocardiography is vital to acknowledge and predict it and its' complications and also the recent update of the management of it...

Electrical storm (ES) is a medical emergency characterized by repetitive episodes of sustained ventricular arrhythmias (VAs) in a limited amount of time (at least 3 within a 24-h period) leading to repeated appropriate implantable cardioverter defibrillator therapies. The occurrence of ES represents a major turning point in the natural history of patients with structural heart disease being associated with poor short- and long-term survival particularly in those with compromised left ventricular ejection fraction (LVEF) that can develop hemodynamic decompensation and multi-organ failure...

Catecholaminergic polymorphic ventricular tachycardia (CPVT) is a channelopathy characterized by adrenergic mediated ventricular arrhythmia. Untreated CPVT is a malignant syndrome with more than 50% of arrhythmic event and up to 25% of fatal or near-fatal cardiac event at 8 years follow-up. Prevention of sudden cardiac death starts with exclusion of competitive sports. Beta blockers (BB) are the cornerstone pharmacological therapy for prevention of cardiac event in CPVT patients. Dose of BB should be the highest tolerable, preferably nadolol...

Tetralogy of Fallot (TOF) is the most common cyanotic congenital heart disease, with a familial recurrence risk of 3%. Despite the performing of an optimal surgical repair, TOF patients may feature a poor medium and long-term survival rate: atrial re-entrant tachycardia will develop in more than 30% of patients and high-grade ventricular arrhythmias will be seen in about 10% of patients. These life-threatening arrhythmias and consequent sudden death continue to represent serious complications following TOF repair...

Kathryn M Meurs
Arrhythmogenic right ventricular cardiomyopathy is an inheritable form of myocardial disease characterized most commonly by ventricular tachycardias, syncope, and sometimes systolic dysfunction and heart failure. A genetic mutation in the striatin gene has been identified in many affected dogs. Dogs with only one copy of the mutation (heterozygous) have a variable prognosis with many dogs remaining asymptomatic or successfully managed on antiarrhythmic drugs for years. Dogs that are homozygous for the mutation seem to have a worse prognosis...

Arrhythmogenic Right Ventricular Cardiomyopathy (ARVC) is a relatively under-recognized hereditary cardiomyopathy. It is characterized pathologically by fibro-fatty infiltration of right ventricular (RV) myocardium and clinically by consequences of RV electrical instability. Timely intervention with device therapy and pharmacotherapy may help reduce the risk of arrhythmic events or sudden cardiac death. Here, we describe a classic case of a young adult with ARVC and a brief literature review. The patient presented with exertional palpitations and ARVC was suspected after his routine electrocardiogram (EKG) revealed symmetric T wave inversions and possible epsilon waves in right precordial leads...

Danon disease is a rare, X-linked dominant genetic disorder that is caused by defects in the lysosome-associated membrane protein 2 (LAMP2) gene. It manifests predominantly in young males with a classic triad of cardiomyopathy, skeletal myopathy, and intellectual disability. Death from cardiac disease is the ultimate cause of demise in many patients if left untreated. Given the rarity of the condition, the natural history is poorly understood. Here, we present a case report on a 14-year-old Hispanic boy with Danon disease, highlighting major clinical events and diagnostic study findings over a six-year period from age of symptom onset to age of death...

BACKGROUND: Estimation of sudden cardiac death (SCD) risk is an integral part of clinical management of patients with hypertrophic cardiomyopathy (HCM). Identification of novel biomarkers of this disease can provide additional criteria for SCD risk stratification. Soluble suppression of tumorigenicity (sST2) and galectin-3 (Gal-3) are useful biomarkers for prognosis of heart failure (HF). Both of them appear to mediate cardiac fibrosis - an important pathogenetic process in HCM. Data about sST2 and Gal-3 usefulness in patients with HCM are limited...

Catecholaminergic polymorphic ventricular tachycardia (CPVT) is a very rare genetic cardiac channelopathy, which has not been sufficiently studied yet. The first clinical manifestation has been described during the first decade of life, linked to strenuous exercise or acute emotion. The absence of structural heart disease and a family history of possible arrhythmogenic disorder generally guide the diagnosis towards a potential channelopathy. The opportunity to perform an extensive genetic analysis allows physicians to make the correct diagnosis and to optimize clinical management...
