Scientific Reports, 2021 Cardiac dyssynchrony is the proposed mechanism for pacemaker-induced cardiomyopathy, which can be prevented by biventricular pacing. Left bundle branch pacing and His bundle pacing are novel interventions that imitate the natural conduction of the heart ...

Long-term outcomes of His bundle pacing in patients with heart failure with left bundle branch block
Heart, 2018 Objectives His bundle pacing (HBP) can potentially correct left bundle branch block (LBBB). We aimed to assess the efficacy of HBP to correct LBBB and long-term clinical outcomes with HBP in patients with heart failure (HF).

FIRST EXPERIENCE OF DIRECT CONSTANT HIS BUNDLE PACING
Медицинский 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.

Effects of Rhythm and Rate-Controlling Drugs in Patients With Permanent His-Bundle Pacing
Frontiers in Cardiovascular Medicine, 2020 Introduction: Antiarrhythmic drug therapy can affect pacemaker parameters in both the atrial and ventricular myocardium. It is not known whether antiarrhythmic drugs impact His bundle pacing/sensing parameters and His to ventricle (H-V) intervals ...

Restitution characteristics of His bundle and working myocardium in isolated rabbit hearts. [PDF]
PLoS ONE, 2017 The Purkinje system (PS) and the His bundle have been recently implicated as an important driver of the rapid activation rate after 1-2 minutes of ventricular fibrillation (VF).

Nef line bundles over finite fields [PDF]
Int. Math. Res. Not. 2013 (2013), (15): 3490-3508, 2011 We use Totaro's examples of non-semiample nef line bundles on smooth projective surfaces over finite fields to construct nef line bundles for which the first cohomology group cannot be killed by any generically finite covers. This is used to show a similar example of a nef and big line bundle on a smooth projective threefold over a finite field.

On a classification of fat bundles over compact homogeneous spaces [PDF]
Differential Geometry and its Applications, 42(2016), 131-141, 2016 This article deals with fat bundles. Berard-Bergery classified all homogeneous bundles of that type. We ask a question of a possibility to generalize his description in the case of arbitrary G-structures over homogeneous spaces. We obtain necessary conditions for the existence of such bundles.

Programmed His Bundle Pacing [PDF]
Circulation: Arrhythmia and Electrophysiology, 2018 Background: During permanent nonselective His bundle (ns-HB) pacing, it is crucial to confirm HB capture/exclude that only right ventricle (RV) myocardial septal pacing is present. Because the effective refractory period (ERP) of the working myocardium is different than the ERP of the HB, we hypothesized that it should be ...
