Pacing failure caused by automatic pacing threshold adjustment system

Journal of Arrhythmia, 2017
Ventricular capture management is an automatic pacing threshold adjustment algorithm that automatically measures pacing threshold through detection of the evoked response after a pacing stimulus. Although it is principally designed to save device battery

His Bundle Pacing: Rebirth of an Important Technique for Pacing the Intrinsic Conduction System

Cardiovascular Innovations and Applications, 2018
Permanent pacemaker implant is a commonly performed cardiac procedure for treatment of bradycardia or conduction system abnormality. With conventional right ventricular (RV) pacing a lead is implanted at the RV apex or on the RV septum.

Interventional therapies for chronic heart failure: An overview of recent developments

ESC Heart Failure, Volume 12, Issue 2, Page 1081-1094, April 2025.
Abstract Heart failure (HF), the final manifestation of most cardiovascular diseases, has become a major global health concern, affecting millions of individuals. Despite basic drug treatments, patients present with high morbidity and mortality rates. However, recent advancements in interventional therapy have shown promising results in improving the ...

Considerations for drug trials in hypertrophic cardiomyopathy

ESC Heart Failure, Volume 12, Issue 2, Page 1095-1112, April 2025.
Abstract Hypertrophic cardiomyopathy (HCM) is a heterogeneous condition with potentially serious manifestations. Management has traditionally comprised therapies to palliate symptoms and implantable cardioverter‐defibrillators to prevent sudden cardiac death. The need for disease‐modifying therapies has been recognized for decades.

Six transition patterns and seven capture types in different left bundle branch bipolar pacing configurations

Frontiers in Cardiovascular Medicine
AimsThis study aims to explore the different transition patterns and capture types during two bipolar pacing tests based on the selective left bundle branch (LBB) capture determined by the continuous pacing and recording technique.MethodsIn total, 67 ...

Prognostic role of TAPSE to PASP ratio in outpatients with left ventricular systolic dysfunction

ESC Heart Failure, Volume 12, Issue 2, Page 912-922, April 2025.
Abstract Aims Few data are available regarding the role of tricuspid annulus plane systolic excursion to pulmonary artery systolic pressure (TAPSE/PASP), a measurement of right ventricular to pulmonary artery coupling, in patients with chronic heart failure and left ventricular systolic dysfunction.

A Case with no Hemodynamic Benefit from Right Ventricular Anodal Capture during Biventricular Pacing

Journal of Arrhythmia, 2007
This case report describes a patient with a biventricular pacing system in whom right ventricular anodal capture had no hemodynamic benefit. While controlling the ventricular output, three morphologies of the paced QRS complex were obtained: right ...

A phenomap of TTR amyloidosis to aid diagnostic screening

ESC Heart Failure, Volume 12, Issue 2, Page 1113-1118, April 2025.
Abstract Cardiac amyloidosis due to transthyretin (ATTR) remains an underdiagnosed cause of cardiomyopathy. As awareness of the disease grows and referrals for ATTR increase, clinicians are likely to encounter more atypical forms of the condition in clinical practice.

Semaglutide normalizes increased cardiomyocyte calcium transients in a rat model of high fat diet‐induced obesity

ESC Heart Failure, Volume 12, Issue 2, Page 1386-1397, April 2025.
Sequeira et al. reveal how the glucagon‐like peptide‐1 receptor agonist (GLP‐1‐RA) semaglutide restores cardiomyocyte function in rats subjected to a high‐fat/high‐fructose diet (HFD). Employing fluorescence‐ and patch‐clamp technology in isolated cardiac myocytes, they demonstrate that semaglutide reverses HFD‐induced activation of L‐type calcium ...
