The ideal pacing site in the ventricle(s) of patients with atrioventricular (AV) block has been debated for years. Despite considerable technological advances, the optimal ventricular pacing site to mimic normal human ventricular physiology and attain the best haemodynamic response remains elusive.1 Prolonged ventricular dyssynchrony induced by long-term right ventricular (RV) apical pacing is… View more

Electrophysiology & Arrhythmia
Author(s): Stavros Stavrakis , Sunny Po Added: 3 years ago
There are numerous conglomerations of autonomic ganglia on the epicardial surface of the heart, known as ganglionated plexi (GP). These GP have been shown to play a significant role in different arrhythmias, including AF. As such, GP ablation has become an adjunctive procedure in the treatment of AF. This review will present the current data on the significance of GP in arrhythmogenesis and will… View more

Electrophysiology & Arrhythmia
Author(s): Jan M Griffin , Jason N Katz Added: 3 years ago
Prior to the widespread availability of left ventricular assist devices (LVADs), many end-stage heart failure patients were forced to fight over scarce transplant resources or face the reality of impending death. For those considered transplant-ineligible, due to medical or psychosocial factors, symptom palliation and end-of-life care were the only available options. This all changed dramatically… View more

Between Sudden Cardiac Death and Catheter Ablation
Author(s): Josep Brugada , Roberto Keegan Added: 3 years ago
The best clinical approach to managing asymptomatic patients with ventricular pre-excitation has yet to be established. The clinical benefit of identifying and treating asymptomatic patients at risk of sudden cardiac death (SCD) has been debated since catheter ablation became effective and safe for the treatment of accessory pathways (APs). Data supporting current recommendations are mostly… View more

Electrophysiology & Arrhythmia
Author(s): Konstantinos D Rizas , Wolfgang Hamm , Stefan Kääb , et al Added: 3 years ago
Experimental and clinical studies have demonstrated that enhanced sympathetic autonomic nervous system (SANS) activity can destabilise myocardial repolarisation,1–4 increasing vulnerability to developing fatal cardiac arrhythmias.5–8 Accordingly, assessment of SANS activity has always been a major goal for cardiac risk stratification methods. Various non-invasive methods including assessment of… View more

Electrophysiology & Arrhythmia
Author(s): Cristina E Molina , Jordi Heijman , Dobromir Dobrev Added: 3 years ago
Optimal cardiac function depends on appropriate rate and force of contraction, with specific cardiac regions having developed particular beat-to-beat properties depending on their individual functions. For example, isovolumetric contraction time is shorter in the right ventricle (RV) than in the left ventricle (LV). At the cellular level, cardiac function is regulated by regional cardiomyocyte… View more
