Effects of atrial fibrillation on the arterial fluid dynamics: a modelling perspective [PDF]

Meccanica, published online June 2018, 2018
Atrial fibrillation (AF) is the most common form of arrhythmia with accelerated and irregular heart rate (HR), leading to both heart failure and stroke and being responsible for an increase in cardiovascular morbidity and mortality. In spite of its importance, the direct effects of AF on the arterial hemodynamic patterns are not completely known to ...

Impact of Renal Impairment on Beta-Blocker Efficacy in Patients With Heart Failure. [PDF]

, 2019
BACKGROUND: Moderate and moderately severe renal impairment are common in patients with heart failure and reduced ejection fraction, but whether beta-blockers are effective is unclear, leading to underuse of life-saving therapy.

Aortic Root Anatomy and Impact on New‐Onset Left Bundle Branch Block After Transcatheter Aortic Valve Implantation

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Angulation of virtual basal ring (VBR), also known as aortic annulus, in relation to sino‐tubular junction (STJ) may lead to greater exposure of implanted stent to the conduction system, consequently increasing the risk of left bundle branch block (LBBB).

Detection of Beat-to-Beat Intervals from Wrist Photoplethysmography in Patients with Sinus Rhythm and Atrial Fibrillation after Surgery [PDF]

, 2017
Wrist photoplethysmography (PPG) allows unobtrusive monitoring of the heart rate (HR). PPG is affected by the capillary blood perfusion and the pumping function of the heart, which generally deteriorate with age and due to presence of cardiac arrhythmia.

Pharmacological analysis of sinus rhythm.

Folia Pharmacologica Japonica, 1993
The SA nodal pacemaker activity is regulated dominantly by autonomic nervous elements, i.e., sympathetic and parasympathetic nervous factors. In addition, circulatory bioactive substances and physicochemical factors also modify changes in sinus rate. Exogenously applied substances exert their actions on sinus rate directly and/or indirectly.

Management of Cardiac Implantable Electronic Devices in Patients With Severe Symptomatic Tricuspid Regurgitation—Proposed Algorithm and Selected Case Examples

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Severe tricuspid regurgitation (TR) is associated with significant morbidity and mortality. Management of severe TR includes treatment of the underlying cause(s), medical therapy and less commonly surgical tricuspid valve repair. Newer transcatheter tricuspid valve repair devices show promise for those patients who remain symptomatic with ...

DeepPlayer: An open‐source SignalPlant plugin for deep learning inference

Software: Practice and Experience, Volume 53, Issue 2, Page 455-464, February 2023., 2023
Abstract Background and Objective Machine learning has become a powerful tool in several computation domains. The most progressive way of machine learning, deep learning, has already surpassed several algorithms designed by human experts. It also applies to the field of biomedical signal processing.

Antithrombotic therapy for heart failure in sinus rhythm [PDF]

Fundamental & Clinical Pharmacology, 2009
AbstractAlthough the risk of thromboembolism in chronic heart failure is high even in the absence of atrial fibrillation, the risk to benefit ratio of anticoagulation vs. antiplatelet therapy or no antithrombotic therapy is poorly defined in this population.

Incidence and 1‐Year Prognostic of Unstable Angina After High‐Sensitivity Troponin Assessment

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Incidence and prognostic of unstable angina after high‐sensitivity troponin assesment is controversial. Aims This study evaluated prognostic of a contemporary population of patients with UA defined using high sensitive T troponin (T hs‐cTn) measurements and with significant coronary artery disease (CAD). Methods Consecutive patients
