Function and Dysfunction of Human Sinoatrial Node [PDF]
Korean Circulation Journal, 2015 Sinoatrial node (SAN) automaticity is jointly regulated by a voltage (cyclic activation and deactivation of membrane ion channels) and Ca(2+) clocks (rhythmic spontaneous sarcoplasmic reticulum Ca(2+) release). Using optical mapping in Langendorff-perfused canine right atrium, we previously demonstrated that the β-adrenergic stimulation pushes the ...

Lithium-Induced Sinoatrial Node Dysfunction [PDF]
Cureus, 2021 Lithium is a common mood-stabilizing drug for manic patients. We describe a case of sinoatrial node dysfunction in a patient with serum lithium levels within the therapeutic range. Given the symptomology and severity of the patient's illness, after placing a permanent pacemaker, the patient was discharged on the preadmission dose of lithium.

Assembly of the Cardiac Pacemaking Complex: Electrogenic Principles of Sinoatrial Node Morphogenesis
Journal of Cardiovascular Development and Disease, 2021 Cardiac pacemaker cells located in the sinoatrial node initiate the electrical impulses that drive rhythmic contraction of the heart. The sinoatrial node accounts for only a small proportion of the total mass of the heart yet must produce a stimulus of ...

Cycle length restitution in sinoatrial node cells: a theory for understanding spontaneous action potential dynamics. [PDF]
PLoS ONE, 2014 Normal heart rhythm (sinus rhythm) is governed by the sinoatrial node, a specialized and highly heterogeneous collection of spontaneously active myocytes in the right atrium.

Junctional Pacemaker May Replace the Sinoatrial Node
Cardiovascular Innovations and Applications, 2021 Junctional rhythm is usually seen in the clinic with different causes. We report a case of bicuspid aortic valve accompanied by sinoatrial node dysfunction.

Sinoatrial-Node Entrance Block [PDF]
Circulation, 1971 Sinus-node function was characterized in 13 patients during cardiac catheterization by the introduction of progressively premature atrial depolarizations. Curves relating the extent of sinus-node depression following these premature depolarizations and their degree of prematurity were constructed.

Bioscience Journal, 2020 Canine distemper is a viral disease that affects several systems on dogs, among them, the cardiovascular system. The aim of this study was to identify canine distemper virus (CDV) in the sinoatrial node (SAN) of dogs serologically positive for distemper
