Successful implantation of a biventricular pacing and defibrillator device via a persistent left superior vena cava [PDF]
Introduction. Persistent left superior vena cava is the most common thoracic venous abnormality which is usually asymptomatic, found incidentally during pacemaker implantation.

Biventricular Stimulation [PDF]
When, in October 1958, the Swedish patient Arne Larsson was expected to die in a desperate scenario of progressive atrioventricular (AV) conduction block with accelerating Stokes-Adams attacks and resuscitation attempts, a team of courageous scientists ventured to implant a pacemaker device ...

Biventricular pacing and heterogeneity of ventricular repolarization in heart failure patients
Objective: The aim of our study was to evaluate the effect of cardiac resyncronization therapy (CRT) on QT dispersion (QTd), JT dispersion (JTd) and transmural dispersion of repolarization (TDR), markers of heterogeneity of ventricular repolarization in ...

Introduction: Biventricular pacing has been the gold standard for cardiac resynchronization therapy in patients with left bundle branch block and severely reduced left ventricular ejection fraction for decades.

Right ventricular (RV) pacing has been reported to result in ventricular dyssynchrony, heart failure, and increased mortality. Pacing associated deterioration of left ventricular (LV) systolic function has been termed pacing-induced cardiomyopathy (PICM).

Dynamics of conduction blocks in a model of paced cardiac tissue [PDF]
We study numerically the dynamics of conduction blocks using a detailed electrophysiological model. We find that this dynamics depends critically on the size of the paced region. Small pacing regions lead to stationary conduction blocks while larger pacing regions can lead to conduction blocks that travel periodically towards the pacing region. We show

Cardiac Electrophysiology Meshfree Modeling through the Mixed Collocation Method [PDF]
We present the meshfree Mixed Collocation Method (MCM) to solve the monodomain model for numerical simulation of cardiac electrophysiology. We apply MCM to simulate cardiac electrical propagation in 2D tissue sheets and 3D tissue slabs as well as in realistic large-scale biventricular anatomies.

Background: Phrenic nerve stimulation (PNS) and high pacing thresholds (HPT) hinder biventricular stimulation in patients (pts) undergoing cardiac resynchronization therapy (CRT). A new quadripolar left ventricular (LV) lead (Quartet 1458Q, St.

Implantable Defibrillators: Which Is the Best Device for Each Patient?
ABSTRACT The first viable alternative to surgical implantation of an epicardial defibrillator system for secondary prevention of sudden cardiac death (SCD) was a single chamber transvenous implantable cardioverter defibrillator (ICD). Thanks to technological advancements over the past 40 years, electrophysiologists now have several options when ...
