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

BACKGROUND: Microvascular rarefaction is a feature of heart failure with preserved ejection fraction (HFpEF) that may underlie associated rhythm disturbances.

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.

Immunocytochemical Demonstration of the Equilibrative Nucleoside Transporter rENT1 in Rat Sinoatrial Node

, 2002
Adenosine exerts multiple receptor-mediated effects in the heart, including a negative chronotropic effect on the sinoatrial node. The aim of this study was to investigate the distribution of the equilibrative nucleoside transporter rENT1 in rat ...

Establishment of cardiac action potential recording using a membrane potential indicator in the mouse sinoatrial node [PDF]

The cardiac action potential in the sinoatrial node is important, as it propagates throughout the heart and determines cardiac rhythm. Because of the anatomical complexity, pacemaker cells in the sinoatrial node can be difficult to identify for ...

Phase response characteristics of sinoatrial node cells

, 2007
In this work, the dynamic response of the sinoatrial node (SAN), the natural pacemaker of the heart, to short external stimuli is investigated using the Zhang et al. model.
