    ..001). Both tachy- and brady-arrhythmias can result from SAN micro-reentry. Postinfarction remodeling, including increased intranodal fibrosis and heterogeneity of refractoriness, provides substrates for SAN reentry. ..

    ..These responses were decreased in amplitude by membrane hyperpolarization and either reversed polarity or declined to zero amplitude at about -80 mV, suggesting the inhibition of a potassium conductance. ..

    ..Our findings support the hypothesis that nitric oxide and carbon monoxide are modulators of neurotransmission in cardiac ganglia and in neural control of the adult human heart. ..

    ..After ablation of persistent atrial flutter, there is temporal recovery of CSNRT and increase in spontaneous atrial activity. These findings suggest that atrial flutter induces reversible changes in sinus node function. ..
  7. Kumar P, Kusumoto F, Goldschlager N. Bradyarrhythmias in the elderly. Clin Geriatr Med. 2012;28:703-15 pubmed publisher
    ..In particular, comprehensive assessment before decisions on medical and device-based management is critical and must take into account social issues and the presence of comorbid conditions. ..

    ..Application of this integrated approach will shed new light on the role of the specialized SAN microanatomy in maintaining sinus rhythm. ..
