Selective left bundle branch pacing for pediatric complete heart block
Indian Pacing and Electrophysiology Journal, 2020 Traditionally Right Ventricle has been the preferred site of pacing for the management of symptomatic brady-arrhythmias. The deleterious effect of chronic RV pacing has been shown by several studies.

The use of His bundle pacing for the treatment of painful left bundle branch block syndrome
Clinical Case Reports, 2020 Painful left bundle branch block syndrome is a rare disorder in which patients develop typical angina‐like pain without identifiable ischemia. To date, there have been few published cases of effective treatment.

ESC Heart Failure, 2021 Aims His–Purkinje conduction system pacing (HPCSP) utilizing His (HBP) or left bundle branch pacing (LBBP) in patients with atrial fibrillation (AF) and wide QRS duration has not been well studied.

On the stability of syzygy bundles [PDF]
arXiv, 2009 We are concerned with the problem of the stability of the syzygy bundles associated to base point free vector spaces of forms of the same degree d on the projective space of dimension n. We deduce directly, from Mark Green's vanishing theorem for Koszul cohomology, that any such bundle is stable if his rank is sufficiently high. With a similar argument,

A Tannakian approach to dimensional reduction of principal bundles [PDF]
, 2016 Let $P$ be a parabolic subgroup of a connected simply connected complex semisimple Lie group $G$. Given a compact K\"ahler manifold $X$, the dimensional reduction of $G$-equivariant holomorphic vector bundles over $X\times G/P$ was carried out by the first and third authors.

A CLINICAL CHALLENGE OVERCOME BY HIS BUNDLE PACING
Journal of the American College of Cardiology, 2019 We highlight a diagnostic challenge in a patient with dyspnea on exertion due to radiation therapy–induced severe first-degree atrioventricular block and how permanent His bundle pacing was helpful in overcoming these symptoms. (Level of Difficulty: Intermediate.)

Generalized Cheeger-Gromoll Metrics and the Hopf map [PDF]
arXiv, 2008 We show, using two different approaches, that there exists a family of Riemannian metrics on the tangent bundle of a two-sphere, which induces metrics of constant curvature on its unit tangent bundle. In other words, given such a metric on the tangent bundle of a two-sphere, the Hopf map is identified with a Riemannian submersion from the universal ...

Simple vector bundles on plane degenerations of an elliptic curve [PDF]
arXiv, 2009 In 1957 Atiyah classified simple and indecomposable vector bundles on an elliptic curve. In this article we generalize his classification by describing the simple vector bundles on all reduced plane cubic curves. Our main result states that a simple vector bundle on such a curve is completely determined by its rank, multidegree and determinant.

Cardiac resynchronization therapy with His bundle pacing
Pacing and Clinical Electrophysiology, 2019 AbstractAimsA novel therapy offering cardiac resynchronization therapy (CRT) with an additional lead placed in His bundle has been reported in a few case reports and case series as improving the hemodynamical and clinical condition of patients with permanent atrial fibrillation (AF) in whom other therapeutic methods have not been successful ...
