Development and Validation of a Novel Contact Force‐Integrated Pulsed Field Quantization Index for Pulmonary Vein Isolation in a Porcine Model

Journal of Cardiovascular Electrophysiology, EarlyView.
A two‐phase pre‐clinical porcine study was performed to develop and validate the Pulsed Field Quantisation Index (PFQI), the first bipolar‐specific ablation index integrating real‐time contact force (CF), pulse‐train number, delivery voltage, and impedance variation for bipolar pulsed field ablation (PFA).

Orchestrated molecular changes of proliferative, migratory‐fibrillar, synaptic, and postmigratory compartments align with precocious cortex‐type specification in the early human pallium

Journal of Anatomy, EarlyView.
Early human cortical development is organized by transient cellular compartments that define cortical types before mature layers form. Analysis of the human fetal pallium (7.5–15 PCW) shows distinct spatiotemporal trajectories for the archicortex, mesocortex, and neocortex, with delayed but accelerated differentiation in allocortical regions.

Liver X Receptor/Retinoid X Receptor Pathway Plays a Regulatory Role in Pacing‐Induced Cardiomyopathy

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2019
Background The molecular mechanisms through which high‐demand pacing induce myocardial dysfunction remain unclear. Methods and Results We created atrioventricular block in pigs using dependent right ventricular septal pacing for 6 months ...

Left ventricular outflow tract obstruction appearing in remote period of right ventricular septal pacing in patient with left ventricular septal bulge

BMJ Case Reports
A woman in her 70 s presented with fatigue and dyspnoea during exertion. Six years ago, she had been implanted with a dual chamber pacemaker with the lead placement at the high septal site of the right ventricle. Echocardiography demonstrated the presence of the previously detected left ventricular septal bulge along with a newly observed systolic ...

A Statistical Model for Risk Stratification on the Basis of Left Ventricular Ejection Fraction and Heart-Rate Turbulence [PDF]

, 2000
The MPIP data set was used to obtain a model for mortality risk stratification of acute myocardial infarction patients. The predictors heart rate turbulence (HRT) and left-ventricular ejection fraction (LVEF) were employed. HRT was a categorical variable

Jugular Versus Femoral Venous Access for Leadless Pacemaker Implantation: A Systematic Review and Meta‐Analysis

Pacing and Clinical Electrophysiology, EarlyView.
ABSTRACT Background Leadless pacemakers (LPMs) have been shown to reduce complications compared with conventional transvenous pacing. Transfemoral venous access (FA) is the standard implantation approach; however, the transjugular approach (JA) has recently emerged as an alternative strategy, but comparative evidence remains limited.

Different lead locations guided by fluoroscopy and ECG parameters and their effect on patients functional status

The Egyptian Heart Journal, 2019
Background Right ventricular apical pacing with the resultant left ventricular dyssynchrony often leads to depressed systolic function and heart failure.

Triple-site pacing for cardiac resynchronization in permanent atrial fibrillation – Acute phase results from a prospective observational study

Revista Portuguesa de Cardiologia, 2016
Introduction and Aim: Multi-site pacing is emerging as a new method for improving response to cardiac resynchronization therapy (CRT), but has been little studied, especially in patients with atrial fibrillation.
