Correlation analysis of the relationship between B-type natriuretic peptide and selected echocardiographic parameters in patients with permanent pacemakers

Studia Medyczne, 2016
Introduction: The present study was undertaken to evaluate the practical value of BNP measurements and echocardiographic left ventricular volume index in patients with permanent pacemakers because there are no such reports in the literature.

Incidence of Bleeding‐Related Complications During Primary Implantation and Replacement of Cardiac Implantable Electronic Devices

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2017
BackgroundUse of cardiac implantable electronic devices (CIEDs) is increasing. The incidence of bleeding‐related complications during CIED procedures and the association with subsequent infection risk have been studied in trial settings but not in ...

An Alternative to Transvenous Lead Extraction in Selected Patients with CIED Infections—A Retrospective Outcome Study

Hearts, 2022
Cardiac implantable electronic device (CIED) implants are rising in an older, more co-morbid population. The prevalence of CIED infection ranges from 1–4%. Whilst complete extraction of all transvenous hardware is recommended for infected, eroded, or pre-

Minimum Active Component Count Design of a PI^λD^μ Controller and Its Application in a Cardiac Pacemaker System

Journal of Low Power Electronics and Applications, 2023
A generalized structure for implementing fractional-order controllers is introduced in this paper. This is achieved thanks to the consideration of the controller transfer function as a ratio of integer and non-integer impedances.

Cardiac Magnetic Resonance, Electromechanical Activation, Kidney Function, and Natriuretic Peptides in Cardiac Resynchronization Therapy Upgrades

Journal of Cardiovascular Development and Disease, 2023
As the mechanism for worse prognosis after cardiac resynchronization therapy (CRT) upgrades in heart failure patients with RVP dependence (RVP-HF) has clinical implications for patient selection and CRT implementation approaches, this study’s objective ...

Setting the pace: new insights into central pattern generator interactions in box jellyfish swimming [PDF]

, 2011
Central Pattern Generators (CPGs) produce rhythmic behaviour across all animal phyla. Cnidarians, which have a radially symmetric nervous system and pacemaker centres in multiples of four, provide an interesting comparison to bilaterian animals for ...

Cardiomyocyte Progenitor Cells as a Functional Gene Delivery Vehicle for Long-Term Biological Pacing

Molecules, 2019
Sustained pacemaker function is a challenge in biological pacemaker engineering. Human cardiomyocyte progenitor cells (CMPCs) have exhibited extended survival in the heart after transplantation.

Cardiac Pacemakers [PDF]

, 2011
Clinical usage of artificial pacing dates back to 1958, when the battery powered cardiac pacemakers became available. Modern implantable pacemakers are the complicated electronic devices operating 10 years continuously without battery exchange.

Real-life ambulatory performance of leadless AV synchronous pacemakers - are all questions answered? [PDF]

, 2023
The latest generation of leadless pacemakers is able to provide atrio-ventricular synchrony (AVS). The performance of these devices regarding ambulant AVS is still under debate.
