Bundling Decisions by a Multiproduct Monopolist with Incomplete Information [PDF]

open access: yes, 1983
This paper analyzes bundling decisions of a rnultiproduct monopolist facing uncertain demand. The monopolist sells his products using an auction mechanism and the market is analyzed as a game with incomplete information in which the buyers as well as ...

TECHNICAL FEATURES OF ELECTRODE IMPLANTATION AND REMOVAL WITH CONSTANT HIS BUNDLE ELECTROCARDIOSTIMULATION

open access: yesИнновационная медицина Кубани, 2019
Background. Clinical search for modern, more hemodynamically efficient areas for placing endocardial electrodes with constant cardiostimulation. Our aim is to study electrophysiological parameters and clinical results of His bundle direct stimulation ...

Electrode Model and Simulation of His- Bundle Pacing for Cardiac Resynchronization Therapy

open access: yesCurrent Directions in Biomedical Engineering, 2020
A disturbed synchronization of the ventricular contraction can cause a highly developed systolic heart failure in affected patients with reduction of the left ventricular ejection fraction, which can often be explained by a diseased left bundle branch ...

Ultra‐high‐density mapping to guide effective His‐bundle pacing

open access: yesClinical Case Reports, 2021
Permanent His bundle pacing is a physiological alternative to right ventricular pacing, resulting in a lower probability of pacing‐induced cardiomyopathy and left ventricular ejection fraction deterioration. The combined use of UHD mapping systems allows

FIRST EXPERIENCE OF DIRECT CONSTANT HIS BUNDLE PACING

open access: yesМедицинский вестник Юга России, 2016
Objective: to study electrophysiological parameters and clinical results of direct constant His bundle pacing (HBP). Materials and methods: we examined 36 patients, divided into 2 equal groups (of 18 patients) according to the type of pacing.

His bundle activates faster than ventricular myocardium during prolonged ventricular fibrillation. [PDF]

open access: yesPLoS ONE, 2014
The Purkinje fiber system has recently been implicated as an important driver of the rapid activation rate during long duration ventricular fibrillation (VF>2 minutes).

The Gouaux-Ashman Phenomenon: His Bundle Recordings [PDF]

open access: yes, 1973
In conclusion, it is important to state the use of His bundle-electrocardiography in differentiating supraventricular beats with aberration from ventricular beats requires a critical approach to the interpretations of deflections appearing in the P-R ...

Permanent His‐Bundle pacing in a patient with advanced conduction system disease: What is the mechanism of QRS narrowing?

open access: yesClinical Case Reports, 2018
Key Clinical Message QRS narrowing during permanent His‐bundle pacing is primarily thought to result from longitudinal dissociation within the His bundle.

Atriofascicular Mahaim with Ebstein anomaly: A case report

open access: yesJournal of Arrhythmia, 2017
We report a case of a 7-year-old girl with atriofascicular Mahaim (AFM) pathway concomitant with Ebstein's anomaly. The QRS wave showed left bundle branch block pattern on electrocardiogram. Holter electrocardiogram showed prolongation of the PR interval

The Critical Use of the His Bundle Electrogram [PDF]

open access: yes, 1973
The technique for electrode catheter recording of consistent and stable His bundle activity presently used in the clinical laboratory was initially developed as an investigational tool.
