Changes in Ion Channel Gene Expression Underlying Heart Failure-Induced Sinoatrial Node Dysfunction [PDF]

Circulation: Heart Failure, 2011
Background— Heart failure (HF) causes a decline in the function of the pacemaker of the heart—the sinoatrial node (SAN). The aim of the study was to investigate HF-induced changes in the expression of the ion channels and related proteins underlying the pacemaker activity of the SAN.

The Sinoatrial Node and Its Dysfunction

1987
The purpose of this chapter is to review the function and dysfunction of the sinoatrial node (SAN). The majority of the chapter encompasses SAN dysfunction: surface electrocardiography; clinical manifestations; noninvasive evaluation; intracardiac electrophysiology and treatment.

Vnitrni lekarstvi, 1994
The authors present a group of 67 patients, mean age 63 +/- 15 years, where they applied on account of suspected dysfunction of the sinoatrial node (SA) the atropine test (AT), 24-hour Holter monitoring and transoesophageal stimulation of the atria (TESP). The objective of the investigation was to test the reliability and yield of the mentioned methods

Klinicheskaia meditsina, 2003
Sick sinus syndrome is characterized by disturbance of its automatic function and (or) sinu-atrial conductivity caused by organic or vegetative defects. Diagnostic algorithm includes: clinical evidence, ECG, Holter monitoring, electrophysiological investigation, pharmacological test. Treatment is pharmacological and surgical.

[Analysis of cardiac rhythm variability in patients with sinoatrial node dysfunction].

Klinicheskaia meditsina, 2010
The study was designed to elucidate the wave structure of heart rhythm variability (HRV) for the assessment of vegetative regulation of pacemaker activity of the sinoatrial node in 362 patients with coronary heart disease. The results were compared with the data of routine cardiologic examination.

[Lengthening of the direct sinoatrial conduction time: a criterion of sinus node dysfunction].

Archives des maladies du coeur et des vaisseaux, 1984
In order to determine the significance of prolongation of the direct sinoatrial conduction time (DSACT), an attempt was made to record the sinus node potential in 110 patients which was successful in 84 cases. The DSACT was normal in 45 cases (Group A) and prolonged (over 130 ms) in 39 cases (Group B).
