The Underscreening of Cardiac Amyloidosis in Patients With Pacemakers—A Single Centre Retrospective Audit

Journal of Cardiovascular Electrophysiology, Volume 37, Issue 6, Page 1372-1375, June 2026.
ABSTRACT Background Cardiac amyloidosis is commonly associated with cardiac conduction disease. We sought to determine the prevalence of advanced conduction disease requiring a pacemaker in patients with known cardiac amyloidosis to evaluate current screening practices among patients receiving pacemakers.

Sustained inward current and pacemaker activity of mammalian sinoatrial node

, 2002
Introduction: A novel sustained inward Na+ current ist, which sensitive to Ca2+-antagonists and potentiated by beta-adrenergic stimulation, has been described in pacemaker cells of rabbit, guinea pig, and rat sinoatrial node, as well as rabbit AV node ...

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.

Electrophysiology and pacemaker function of the developing sinoatrial node

, 2007
The sinoatrial node performs its task as a cardiac impulse generator throughout the life of the organism, but this important function is not a constant.

Rhythm Generating Mechanisms in Rat Sinoatrial Node

Current Medical Issues
Background: The major membrane currents responsible for sinoatrial (SA) rhythm generation are generally studied in isolated cardiac cells using electrophysiological tools. Such studies are resource and labor-intensive.

Simplified 2D Bidomain Model of Whole Heart Electrical Activity and ECG Generation

Measurement Science Review, 2014
The aim of this study was the development of a geometrically simple and highly computationally-efficient two dimensional (2D) biophysical model of whole heart electrical activity, incorporating spontaneous activation of the sinoatrial node (SAN), the ...

Ageing-related changes of connexins and conduction within the sinoatrial node

, 2004
Clinical studies have shown that sinoatrial node dysfunction occurs at the highest incidence in the elderly population. Guinea-pigs were studied throughout their lifespan (i.e.

Stress-induced pacemaker desynchronization in the sinoatrial node

Frontiers in Cardiovascular Medicine
The sinoatrial node (SAN) functions as a heterogeneous population of electrically coupled pacemaker cells rather than as a single dominant oscillator.
