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

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

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

The heterozygous mutation c.155G > T in GNB2 clinically leads to sinus bradycardia and sinus node dysfunction. Here, patient-specific skin fibroblasts of the mutation carrier were used for Sendai virus reprogramming into human induced-pluripotent stem ...

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

Lacosamide-induced sinus node dysfunction followed by severe agranulocytosis [PDF]
Background Lacosamide (LCM) is the antiepileptic drug approved by the U.S. Food and Drug Administration in 2008 that facilitates slow activation of the voltage-gated sodium channels.

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

Pheochromocytoma and sinus node dysfunction [PDF]
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.
