Predictive factors of atrioventricular conduction disorders [PDF]
Romanian Medical JournalAtrioventricular conduction disorders represent an alteration in the normal function of the heart’s electrical conduction system, a system that connects the atria and ventricles through the atrio-ventricular node and the His-Purkinje system. Consequently,

Hitting the Wall: The Hidden Challenge of 2:1 Block in Pacemaker Patients
Pacing and Clinical Electrophysiology, EarlyView.ABSTRACT Introduction Dual‐chamber pacemakers incorporate proprietary algorithms to optimize atrioventricular (AV) synchronization and prevent pacemaker‐mediated arrhythmias. Patients have recently presented to our center with severe exercise intolerance due to the early onset of 2:1 AV block caused by Biotronik's Auto‐PVARP and 2:1 Lock‐in protection ...

Diastolic And Systolic Right Ventricular Dysfunction Precedes Left Ventricular Dysfunction In Patients Paced From Right Ventricular Apex [PDF]
, 2006 Background: Cardiac dysfunction after right ventricular (RV) apical pacing is well known but its extent, time frame of appearance and individual effect on left ventricular (LV), RV systolic and diastolic parameters has not evaluated in a systematic ...

Pacing and Clinical Electrophysiology, EarlyView.ABSTRACT Background and Aims Central venous obstruction (CVO) increases the complexity of pacing interventions, whether it be with device‐associated symptomatic superior vena cava syndrome (SVCS), or by impeding new implants. Endovascular treatment involves the joint expertise of both cardiac pacing and vascular specialists.

Complete Heart Block Lacking Functional Anatomical Impairment in the Conduction System
Pakistan Journal of Medicine and DentistryIntroduction: Complete heart block also known as third-degree atrioventricular block (AV block) is a condition in which there is no conduction of the impulse produce in the sinoatrial node (SA node) in the atrium to the ventricle.1 Complete heart ...

Morphological Substrates for Atrial Arrhythmogenesis in a Heart With Atrioventricular Septal Defect
Frontiers in Physiology, 2018 Due to advances in corrective surgery, congenital heart disease has an ever growing patient population. Atrial arrhythmias are frequently observed pre- and post-surgical correction. Pharmaceutical antiarrhythmic therapy is not always effective, therefore

Pacing and Clinical Electrophysiology, EarlyView.ABSTRACT Background Left bundle branch block (LBBB) and right ventricular pacing (RVP) are associated with abnormal myocardial mechanics and cardiomyopathy. Consequently, chronic LBBB may increase the risk of heart failure and mortality in patients undergoing RVP.

Experimental Physiology, EarlyView.Abstract The common hippopotamus (Hippopotamus amphibius) shares a common terrestrial ancestor with whales (Cetacea) and has independently evolved similar physiological adaptations to their aquatic lifestyle. Although several studies have explored the electrical signalling in whale hearts, the understanding of the conduction system and electrical ...
