Ultra-High-Frequency ECG in Cardiac Pacing and Cardiac Resynchronization Therapy: From Technical Concept to Clinical Application

open access: yesJournal of Cardiovascular Development and Disease
Identifying electrical dyssynchrony is crucial for cardiac pacing and cardiac resynchronization therapy (CRT). The ultra-high-frequency electrocardiography (UHF-ECG) technique allows instantaneous dyssynchrony analyses with real-time visualization.

Biventricular Pacing Cardiac Contractility Modulation Improves Cardiac Contractile Function via Upregulating SERCA2 and miR-133 in a Rabbit Model of Congestive Heart Failure

open access: yesCellular Physiology and Biochemistry, 2014
Objective: To compare the effects of biventricular electrical pacing and conventional single-ventricular pacing for cardiac contractility modulation (CCM) on cardiac contractile function and to delineate the underlying molecular mechanisms.

In the Search of Noninvasive Methods Delineating Left Bundle Branch Block Amendable With Conduction System Pacing

open access: yesPacing and Clinical Electrophysiology, EarlyView.
ABSTRACT Conduction system pacing (CSP) is an emerging new method of cardiac resynchronization therapy (CRT), however, one third of patients with left bundle branch block (LBBB) have distal conduction disease, which is not amenable to correction with CSP. There is an emerging need for tailored analysis of ventricular depolarization patterns for patient

Permanent His Bundle Pacing: Electrophysiological and Echocardiographic Observations From Long-Term Follow-Up [PDF]

open access: yes, 2017
Background Permanent His bundle pacing (HBP) is a physiological alternative to right ventricular pacing. It is not known whether HBP can cause His-Purkinje conduction (HPC) disease.

QT Interval Evaluation in Right Ventricular Pacing: Validation of a Novel Formula

open access: yesPacing and Clinical Electrophysiology, EarlyView.
Abstract Background QT interval measurement in the presence of right ventricular pacing (RVP) represents a clinical challenge. We therefore aimed to derive and validate a formula for QT estimation during RVP in a large cohort of pacemaker patients. Methods and Results We prospectively enrolled 100 patients in a derivation cohort and 487 in a validation

The “Missing” Link Between Acute Hemodynamic Effect and Clinical Response [PDF]

open access: yes, 2011
The hemodynamic, mechanical and electrical effects of cardiac resynchronization therapy (CRT) occur immediate and are lasting as long as CRT is delivered.

Left Bundle Branch Area Pacing Reverts Electromechanical Window Negativity to a Similar Extent as Biventricular Pacing

open access: yesPacing and Clinical Electrophysiology, EarlyView.
BiVP = biventricular pacing; CRT = cardiac resynchronization therapy; EMW = electromechanical window; LBBAP = left bundle branch area pacing; QAoC = Time interval from the onset of the QRS complex to the center of the aortic valve closure artifact; QT = QT interval measured by tangent method.

Echocardiographic Substrate for Biventricular Pacing

open access: yesJournal of the American College of Cardiology, 2015
It is axiomatic that the presence of a substrate that is amenable to a specific treatment, coupled with effective delivery of that treatment, is likely to produce the most favorable clinical outcomes.

Multipoint Pacing Versus Cardiac Resynchronization Therapy in Heart Failure: A Systematic Review and Meta‐Analysis

open access: yesPacing and Clinical Electrophysiology, EarlyView.
ABSTRACT Introduction Multipoint pacing (MPP) delivers sequential stimuli from multiple left‐ventricular electrodes, potentially improving cardiac resynchronization therapy (CRT) response versus conventional biventricular pacing (BiV). We performed an updated systematic review and meta‐analysis to synthesize contemporary evidence.

Temporary epicardial left ventricular and biventricular pacing improves cardiac output after cardiopulmonary bypass

open access: yesJournal of Cardiothoracic Surgery, 2012
Background To evaluate, with different pacing modes, acute changes in left ventricular systolic function, obtained by continuous cardiac output thermodilution in various subsets of patients undergoing cardiopulmonary bypass surgery.
