Sinus arrest in a patient with acute coronary syndrome due to a rare anatomical variation in the sinoatrial nodal artery [PDF]
Background Sinus node dysfunction can occur in patients with acute coronary syndrome (ACS), particularly in inferior myocardial infarction. Because the sinoatrial nodal artery (SANa) shows considerable anatomical variation, ischemia-related sinus arrest ...

D-galactose causes sinoatrial node dysfunction: from phenotype to mechanism. [PDF]
With the population aging, age-related sinoatrial node dysfunction (SND) has been on the rise. Sinoatrial node (SAN) degeneration is an important factor for the age-related SND development. However, there is no suitable animal modeling method in this field.

Sympatho-vagal balance and intrinsic sinoatrial node activity in larval zebrafish quantified by heart rate variability [PDF]
The larval zebrafish is a powerful in vivo model for studying cardiac disease. Alterations in sympatho-vagal balance and intrinsic sinoatrial node activity, key contributors to cardiac dysfunction, can be assessed using heart rate variability (HRV ...

Sinoatrial node dysfunction after stereotactic ablative radiation therapy in the chest.
132 Background: Sinoatrial node (SAN) injury following stereotactic ablative radiation therapy (SABR) in the chest has not been reported in the literature. We report SAN dysfunction as a potential toxicity of SABR in the chest. Methods: We examined the clinical courses and SABR plans of 47 patients treated for T1 or T2 non-small cell lung cancer of ...

Pathophysiology of Cav1.3 L-type calcium channels in the heart
Ca2+ plays a crucial role in excitation-contraction coupling in cardiac myocytes. Dysfunctional Ca2+ regulation alters the force of contraction and causes cardiac arrhythmias. Ca2+ entry into cardiomyocytes is mediated mainly through L-type Ca2+ channels,

Aging and Sinoatrial Node Dysfunction [PDF]
In the century since the discovery by Keith and Flack of the sinoatrial node in the mole heart, a detailed mosaic of its cellular, anatomic, and electrophysiological properties has emerged. The human sinus node has been found to be anatomically constant and well localized, occupying an approximately 10-mm subepicardial region on the sulcus terminalis ...

A Case of Complete AV Blockade in Patient with Lyme Borreliosis
Lyme disease (tick-borne borreliosis) is an infectious vector-borne natural focal disease that tends to a chronic and recurrent course with a predominant damage to the skin, nervous system, musculoskeletal system and heart. Cardiac features is manifested,

Metabolic syndrome remodels electrical activity of the sinoatrial node and produces arrhythmias in rats. [PDF]
In the last ten years, the incidences of metabolic syndrome and supraventricular arrhythmias have greatly increased. The metabolic syndrome is a cluster of alterations, which include obesity, hypertension, hypertriglyceridemia, glucose intolerance and ...
