His–Purkinje Conduction System Pacing: State of the Art in 2020
Author(s): Ahran D Arnold , Zachary I Whinnett , Pugazhendhi Vijayaraman Added: 3 years ago
Right ventricular apical pacing (RVAP) results in dyssynchronous ventricular activation that can lead to impairment of ventricular function. Alternative myocardial pacing sites such as RV septal pacing (RVSP) and RV outflow tract pacing still rely on myocardial cell-to-cell conduction and have not been shown to prevent pacing-induced cardiomyopathy.1 Biventricular pacing (BVP) certainly improves… View more

Atrioventricular Nodal Reentrant Tachycardia
Author(s): Demosthenes G Katritsis , Mark E Josephson Added: 3 years ago
Atrioventricular nodal reentrant tachycardia (AVNRT) denotes re-entry in the area of the AV node, and represents the most common regular arrhythmia in the human.1 Although several models have been proposed to explain the mechanism of the arrhythmia in the context of the complex anatomy and the anisotropic properties of the atrioventricular (AV) node and its atrial extensions (see Figure 1),2 the… View more

Electrophysiology & Arrhythmia
Author(s): Ethan R Ellis , Mark E Josephson Added: 3 years ago
Cardiomyopathies are heterogeneous heart muscle disorders with a wide range of aetiologies and clinical manifestations. They are often defined by their causes (i.e. hypertension, prior myocardial infarction, valvular heart disease), although current major society definitions describe cardiomyopathy as the presence of abnormal myocardial structure and/or function in the absence of underlying… View more

Pacing and Defibrillators in Complex Congenital Heart Disease
Author(s): Henry Chubb , Mark O’Neill , Eric Rosenthal Added: 3 years ago
Device therapy is increasingly employed in the management of complex congenital heart disease (CHD). Bradycardias, most often related to sinus nodal dysfunction (SND) or atrioventricular nodal (AVN) block, may necessitate the implantation of pacing devices, while malignant arrhythmias may be treated by appropriate use of implantable cardioverter defibrillators (ICDs). However, there is a complex… View more

Heart Failure
Author(s): Jorge G Panizo , Sergio Barra , Greg Mellor , et al Added: 3 years ago
Premature ventricular complexes (PVCs) are the most common ventricular arrhythmia. Their prognostic significance cannot be interpreted without considering the presence or absence of any associated underlying cardiac condition. In the absence of structural heart disease, PVCs were generally considered to be benign.1,2 In the 1970s and 1980s, it was postulated that frequent PVCs could be a trigger… View more

Limitations in Mapping Ventricular Tachycardia
Author(s): Adam J Graham , Michele Orini , Pier D Lambiase Added: 3 years ago
Recurrent episodes of ventricular tachycardia (VT) in patients with structural heart disease are associated with increased mortality and morbidity, despite the life-saving benefits of implantable cardiac defibrillators (ICDs).1,2 Because ICD therapies are abortive and do not alter the underlying arrhythmogenic substrate, their reduction becomes important, especially as recurrent shocks can cause… View more
