Sinus Node Dysfunction, Atrial Arrhythmias, and the Sinus Node Microcirculation

Clinical Medicine Insights: Case Reports, 2022
A patient with sinus node dysfunction (SND) developed atrial arrhythmias that were abolished after avoidance of nonsteroidal anti-inflammatory medication and by the institution of a deliberate, modest increase in blood pressure, suggesting that there was

Ventricular pacing or dual-chamber pacing for sinus-node dysfunction [PDF]

New England Journal of Medicine, 2002
BACKGROUND Dual-chamber (atrioventricular) and single-chamber (ventricular) pacing are alternative treatment approaches for sinus-node dysfunction that causes clinically significant bradycardia.

PITX2 dosage-dependent changes in pacemaker cell state underlie sinus node dysfunction and atrial arrhythmias [PDF]

Nature Communications
Physiologically relevant increases in transcription factor dosage and their role in development and disease remain largely unexplored. Genomic deletions upstream of the Paired-like homeodomain transcription factor gene (PITX2), identified in patients ...

Oral theophylline corrects sinus node dysfunction in acute on chronic lithium toxicity: case report and systematic review of lithium-induced Sinus node dysfunction [PDF]

Frontiers in Cardiovascular Medicine
IntroductionLithium is a well-known agent to cause systemic toxicity with its narrow therapeutic window. Toxic cardiac effects are known but seldomly reported and can manifest as sinus node dysfunction (SND) ranging from delayed conduction to sinus ...

Use of machine learning and Poincaré density grid in the diagnosis of sinus node dysfunction caused by sinoatrial conduction block in dogs [PDF]

Journal of Veterinary Internal Medicine
Background Sinus node dysfunction because of abnormal impulse generation or sinoatrial conduction block causes bradycardia that can be difficult to differentiate from high parasympathetic/low sympathetic modulation (HP/LSM).

A case report of sinus node–sparing hybrid ablation for refractory sinus tachycardia following cardioneuroablation for sinus node dysfunction [PDF]

BMC Cardiovascular Disorders
Background Cardioneuroablation (CNA) is increasingly used worldwide in the treatment of functional bradyarrhythmia mediated by excessive vagal tone. However, a potential early or long-term complication is the development of postprocedural inappropriate ...

Cardioneuroablation for the Treatment of Hypervagotonic Sinus Node Dysfunction [PDF]

JACC: Case Reports
Hypervagotonic sinus node dysfunction (SND) is a form of SND with sinus bradycardia caused by enhanced vagal tone. Indirect proof of hypervagotonia as the mechanism can be inferred from resolution of bradycardia following atropine infusion.

Sinus node dysfunction following bariatric surgery: A case report [PDF]

SAGE Open Medical Case Reports
Sinus node dysfunction is often due to degeneration of the heart’s impulse-generating system. We report a case of a 40-year-old woman with a recent gastric sleeve surgery, who presented with symptomatic sinus bradycardia following significant post ...

Sinus node dysfunction

The Nurse Practitioner, 2012
Sinus node dysfunction (SND) refers to a wide range of abnormalities involving sinus node and atrial impulse generation and propagation. SND occurs at any age and is commonly encountered in clinical practice. Clinicians must be able to accurately diagnose this syndrome, which can present from asymptomatic bradycardia to atrial standstill.

Selection of patients with symptomatic vagal-induced sinus node dysfunction: Who will be the best candidate for cardioneuroablation?

Frontiers in Physiology, 2023
Sinus node dysfunction is a multifaceted disorder with variable manifestations, the prevalence of which increases with age. In a specific group of patients, excessive vagal activity may be the sole cause for this condition.
