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 ...

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, 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

Pheochromocytoma and sinus node dysfunction [PDF]

Baylor University Medical Center Proceedings, 2019
Pheochromocytomas are rare catecholamine-producing neuroendocrine tumors that can lead to detrimental outcomes; if identified and treated, they are associated with a good prognosis. The clinical presentation can vary greatly but is classically associated with tachycardia, headaches, and hypertension.

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 ...

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 ...

Brugada syndrome and sinus node dysfunction

Journal of Arrhythmia, 2018
AbstractBrugada syndrome (BrS) is a well‐known catastrophic disease first reported in 1992 by the Brugada brothers. Ventricular fibrillation (VF) is an essential arrhythmia in BrS. An association between BrS and atrial tachyarrhythmias is not uncommon. However, sinus node dysfunction (SND) associated with BrS has not been well discussed. In this review,

Sinus Node Dysfunction Secondary to Hyperparathyroidism

Journal of Cardiovascular Pharmacology and Therapeutics, 2004
We present two patients who were diagnosed with symptomatic sinus node dysfunction in the setting of hypercalcemia secondary to hyperparathyroidism. An extensive review of the literature has not revealed previous reports of this pathologic process.

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 ...
