Early Repolarization Syndrome

Malignant early repolarization as cause of sudden death has taken on great importance in recent years. It has been described as an entity capable of producing ventricular arrhythmic events, causing from episodes of syncope to sudden cardiac death. Ventricular fibrillation is the typical arrhythmia in these patients, with no clear relationship to date with idiopathic monomorphic ventricular tachycardia. Electrocardiographic markers related to the development of arrhythmic events in early repolarization syndrome have been described. They seem not only related to the development of ventricular fibrillation, but also to sustained monomorphic ventricular tachycardia, as is the case described in the article.

Monomorphic ventricular tachycardia (VT) may occur in the presence or absence of structural heart disease. The standard therapy for patients with structural heart disease at high risk of sudden cardiac death due to VT is the implantable cardioverter defibrillator (ICD). While ICDs effectively terminate VT and prevent sudden cardiac death, they do not prevent recurrent episodes of VT, since the underlying arrhythmogenic substrate remains unchanged. However, shocks from an ICD increase mortality and impair quality of life. These limitations as well as continuous advancements in technology have made catheter ablation an important treatment strategy for patients with structural heart disease presenting with VT. Idiopathic ventricular arrhythmias include premature ventricular contractions and VT occurring in the absence of overt structural heart disease. In this setting, catheter ablation has evolved as the primary therapeutic option for symptomatic ventricular premature beats and sustained VTs and is curative in most cases. This chapter presents an overview of the principles of invasive diagnosis and treatment of monomorphic VTs in patients with and without structural heart disease and delineates the clinical outcome of catheter ablation. Finally, the chapter provides an outlook to the future, discussing potential directions and upcoming developments in the field of catheter ablation of monomorphic VT.

Holter Monitoring

A 50-year-old female patient admitted for etiological syncope investigation. A 24-hour Holter was installed where the record showed the mechanism of sudden cardiac death. Sudden bradycardia caused by paroxysmal atrioventricular block led to torsades de pointes, ventricular fibrillation and death. This case shows the importance of Holter in the chronology of arrhythmic events that lead to sudden death and highlights a poorly reported event – the occurrence of cardiac death during 24-hour Holter monitoring.

Pumping Activity

Cardiac arrest occurs when there is abrupt cessation of effective pumping activity of the heart. Among the likely causes are ventricular asystole (electrical or mechanical), pulseless ventricular tachycardia or ventricular fibrillation. Clinically this may present as ‘sudden cardiac death’.

AbstractEarly repolarization pattern (ERP), a form of J-wave syndromes, was considered long time a benign ECG phenomenon. However, recent data confirmed that certain phenotypes of ERP are related to an increased risk of sudden cardiac death (idiopathic ventricular fibrillation). Our paper gives a short and practical update regarding the main issues related to ERP: epidemiological data, molecular and electrophysiological background, clinical significance and risk stratification. At the end, the future directions of research and clinical management related to ERP are presented.

Malignant Arrhythmias

Abstract Syncope in patients with Brugada electrocardiogram pattern may represent a conundrum in the decision algorithm because incidental benign forms, especially neurally mediated syncope, are very frequent in this syndrome similarly to the general population. Arrhythmic syncope in Brugada syndrome typically results from a self-terminating sustained ventricular tachycardia or paroxysmal ventricular fibrillation, potentially leading to sudden cardiac death. Distinguishing syncope due to malignant arrhythmias from a benign form is often difficult unless an electrocardiogram is recorded during the episode. We performed a review of the existing literature and propose a practical approach for diagnosis and treatment of the patients with Brugada syndrome and syncope.
