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.

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 ...

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 ...

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 ...

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.

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

Six seconds to P wave! Recovered without permanent pacemaker – An enlightening story

IHJ Cardiovascular Case Reports, 2020
Severe symptomatic sinus node dysfunction in obstructive jaundice is known but rarely encountered. Sinus bradycardia in these patients has been attributed to the effect of bile salts on sino-atrial node.
