This study describes methods of volitional management of heart rhythms and proves that it is possible by means of management of its operations, subject to arbitrary control, which also has a strong functional connection to the center of the heart rhythm formation in the brain. Experiments demonstrate that it is possible for arbitrary changes in the heart rhythm to be made through conscious control of the breathing rhythm, and even a short-term cardiac arrest by means of contracting abdominal muscles. We postulate that the management of human heart rhythm is indirectly regulated through arbitrary controlled operations. The present article describes and analyzes ways that enable a human to consciously and purposefully manage the frequency of heart contractions. Common principles of arbitrary management of the heart rhythm in humans are uncovered through analysis.

Background: Abelacimab is a fully human monoclonal antibody that binds to the inactive form of factor XI and blocks its activation. The safety of abelacimab as compared with a direct oral anticoagulant in patients with atrial fibrillation is unknown.
Methods: Patients with atrial fibrillation and a moderate-to-high risk of stroke were randomly assigned, in a 1:1:1 ratio, to receive subcutaneous injection of abelacimab (150 mg or 90 mg once monthly) administered in a blinded fashion or oral rivaroxaban (20 mg once daily) administered in an open-label fashion.

Atrial cardiomyopathy (AC) has been defined by the European Heart Rhythm Association as "Any complex of structural, architectural, contractile, or electrophysiologic changes in the atria with the potential to produce clinically relevant manifestations".1 The left atrium (LA) plays a key role in maintaining normal cardiac function; in fact atrial dysfunction has emerged as an essential determinant of outcomes in different clinical scenarios, such as valvular diseases, heart failure (HF), coronary artery disease (CAD) and atrial fibrillation (AF). A comprehensive evaluation, both anatomical and functional, is routinely performed in cardiac imaging laboratories.

Brugada syndrome (BrS) is a genetic condition that increases the risk of life-threatening arrhythmias, which can result in sudden cardiac death (SCD). Implantable loop recorders (ILRs) have become a key tool in managing patients with unexplained syncope, and guidelines advise their use in individuals with recurrent, unexplained syncope or palpitations. However, the role of ILRs in inherited arrhythmic conditions like BrS remains a topic of debate.

Background: Risk factors and comorbidities can complicate management of non-valvular atrial fibrillation. We describe and compare real-world safety and effectiveness of direct oral anticoagulants (DOACs; apixaban, rivaroxaban, dabigatran) and vitamin K antagonists (VKAs) in subgroups of patients with non-valvular atrial fibrillation at high risk for gastrointestinal (GI) bleeding, utilizing data from a national quasi-exhaustive French database.
Methods: Anticoagulant-naïve adults with non-valvular atrial fibrillation with ≥1 gastrointestinal bleeding risk factor, initiating anticoagulant treatment January 2016-December 2019, and covered by the French national health data system were eligible.

Introduction: Data on circumstances of sudden cardiac arrest (SCA) in Germany are limited. The present study aimed to investigate systematically the current pre- and in-hospital circumstances of a SCA cohort at young age (65 years or younger) in Germany.
Methods: In the period from 2010 to 2021, we enrolled 191 consecutive patients with SCA at a university hospital in the Ruhr area, Germany.
