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 [PDF]
Indian Pacing and Electrophysiology JournalIntroduction: 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.

Aging and Sinoatrial Node Dysfunction [PDF]
Circulation, 2007 In the century since the discovery by Keith and Flack of the sinoatrial node in the mole heart, a detailed mosaic of its cellular, anatomic, and electrophysiological properties has emerged. The human sinus node has been found to be anatomically constant and well localized, occupying an approximately 10-mm subepicardial region on the sulcus terminalis ...

A low dose of amiodarone-indused sinoatrial node dysfunction: a case report
CARDIOMETRY, 2022 We recently treated a case similar to that reported by Mun et al and Chinushi M. Holter ECG demonstrated paroxysmal atrial fibrillation, frequent ventricular ectopy’s, atrial tachycardia. The patient complained of palpitation. We have prescribed and amiodarone (100 mg/day) per day for 2 months. In the second visit, the palpitation attacks were relieved.

Familial sinoatrial node dysfunction. Increased vagal tone a possible aetiology. [PDF]
Heart, 1976 Clinical and electrophysiological studies of a 13-year-old boy with sinus bradycardia revealed sinus node dysfunction. Long-term follow-up data of members of his family indicated familial sinus node dysfucntion. Increased vagal tone was present in all patients.

Atrial fibrillation, sinoatrial and atrioventricular node dysfunction in a mouse model of heart failure with preserved ejection fraction [PDF]
Experimental Physiology, EarlyView.Summary of the timeline of characterized events related to atrial fibrilation (AF) and diastolic dysfunction in a mouse heart failure with preserved ejection fraction (HFpEF) model. Three weeks after the initiation of the diet regimen with high fat diet (HFD) and Nω‐nitro‐l‐arginine methyl ester (l‐NAME) in drinking water to induce HFpEF, significantly

Cycle length restitution in sinoatrial node cells: a theory for understanding spontaneous action potential dynamics. [PDF]
PLoS ONE, 2014 Normal heart rhythm (sinus rhythm) is governed by the sinoatrial node, a specialized and highly heterogeneous collection of spontaneously active myocytes in the right atrium.

Pathophysiology of Cav1.3 L-type calcium channels in the heart
Frontiers in Physiology, 2023 Ca2+ plays a crucial role in excitation-contraction coupling in cardiac myocytes. Dysfunctional Ca2+ regulation alters the force of contraction and causes cardiac arrhythmias. Ca2+ entry into cardiomyocytes is mediated mainly through L-type Ca2+ channels,

Are physiological oscillations physiological?
The Journal of Physiology, EarlyView., 2023 Abstract figure legend Mechanisms and functions of physiological oscillations. Abstract Despite widespread and striking examples of physiological oscillations, their functional role is often unclear. Even glycolysis, the paradigm example of oscillatory biochemistry, has seen questions about its oscillatory function.
