Microvascular Rarefaction in the Sinoatrial Node: A Potential Mechanism for Pacemaker Dysfunction in Early HFpEF. [PDF]

JACC. Clinical electrophysiology
Microvascular rarefaction is a feature of heart failure with preserved ejection fraction (HFpEF) that may underlie associated rhythm disturbances. Angiotensin II (AngII) signaling has been implicated, but its role in sinoatrial (SA) node dysfunction remains unclear.The authors tested whether changes in SA node microvascular architecture contribute to ...

The electrophysiological effects of Tongyang Huoxue granules on the ignition phase during hypoxia/reoxygenation injury in sinoatrial node cells

Frontiers in Physiology
IntroductionThis study was undertaken to explore the potential therapeutic effects of Tongyang Huoxue Granules (TYHX) on sinoatrial node (SAN) dysfunction, a cardiac disorder characterized by impaired impulse generation or conduction.

Does Long-Term Sport Practice Facilitate the Development of Idiopathic Bradycardia Requiring Early Pacemaker Implantation During the Course of Life?

Journal of Cardiovascular Development and Disease
Background: Sinus bradycardia and first-/second-degree atrioventricular (AV) block in athletes are traditionally considered secondary to increased vagal tone and therefore reversible.

Atrial fibrillation, sinoatrial and atrioventricular node dysfunction in a mouse model of heart failure with preserved ejection fraction

Experimental Physiology
Millions of people are affected by atrial fibrillation (AF) and heart failure with preserved ejection fraction (HFpEF), two disorders frequently found simultaneously. However, the interrelationship between these intertwined disorders is poorly understood,

Sinus Bradycardia in Endurance Athletes From Physiological Adaptation to Potential Pathology

Quality in Sport
Sinus bradycardia is a common electrocardiographic finding in trained athletes and a hallmark feature of the athlete’s heart. Reduced resting heart rate, particularly in endurance athletes, reflects physiological adaptation to long-term intensive ...

Dual-chamber leadless pacemaker implant via the RIJ after failed femoral vein implant in a 65-year-old patient with symptomatic bradycardia, with left IJ port and right-sided AV fistula

Indian Pacing and Electrophysiology Journal
Introduction: Sinus node dysfunction (SND) is a disorder defined by abnormal initiation and conduction of electrical signals from the sinoatrial node. The preferred first-line treatment for a patient with symptomatic SND is a permanent pacemaker implant.

Metabolic Perturbation Exacerbates Sinoatrial Node Dysfunction in Heart Failure

SUMMARY Heart failure (HF) affects approximately 6.2 million people in the United States, with a 5-year mortality exceeding 50%. Bradyarrhythmia, a known complication in HF due to sinoatrial node (SAN) dysfunction (SAND), increases the morbidity and mortality of HF patients. Insights into the mechanistic underpinnings
