Disease of the sinus node(including sinoatrial block).
Generation of action potential in the heart occursin the sinus node.
Examples include sinus node dysfunction and heart block.
Sinus node dysfunction is treated with a pacemaker.* Heart block.
Leading in the formation of electrical impulses in the myocardium is the sinus node.
The sinus node produces the electrical signals that initiate every heartbeat.
It is determined by the acceleration of the heartbeat with the strengthening of the sinus node.
Sinus Node Dysfunction- An abnormally slow natural"pacemaker" in the heart.
Occasionally, electric task can develop from the left room instead of the sinus node.
Sinus node dysfunction(including sinus rate< 50 bpm).
Sometimes, electrical activity can arise from the left atrium rather than the sinus node.
Its causes lie in the malfunctioning of the sinus node itself or in internal problems.
New impulse centers begin to function independently,going out of control of the sinus node.
Disfunction of the sinus node and synoatric blockages(often with age such disorders occur independently);
A delay or complete block of the electrical impulse as it travels from the sinus node to the ventricles.
If the frequency of impulses from the sinus node exceeds 90, it is customary to talk about sinus tachycardia.
Verapamil is contraindicated in cases of severe impairment of cardiac conduction,weakness of the sinus node.
If you have slow heart rate(high degree heart block or sinus node disease), and don't have a pacemaker fitted.
Stopping the sinus node is a clinically unfavorable condition, as it can provoke the development of sudden cardiac arrest.
Normally, the formation of an electrical pulse occurs in the sinus node, subsequently spreading to the myocardium.
In some people the sinus node problems may result in alternating slow and fast heart rates(bradycardia-tachycardia syndrome).
Does the patient have severe bradycardia, sinus node dysfunction or second and third degree heart block, in the absence of a pacemaker?
With sinus bradycardia, even after exercise, there is no increase in the heart rate,which is due to the presence of factors affecting the sinus node.
Second or third degree atrioventricular(AV)block or sinus node dysfunction, unless these patients have a functioning artificial pacemaker.
The sinus node itself is a cluster of cells in the upper right chamber of the heart where these electrical impulses are generated.
For this reason,the atria contract with the frequency of the sinus node, and the ventricles with a frequency much smaller, generated by the bundle of His.
However, even if the sinus node generates impulses with the necessary frequency, due to obstacles in the way(blockades), they will not reach the destination point.
The reason this type of tachycardia is associated with impaired sinus node generating pulses or a violation of the impulses from the sinus node to the ventricles.
In bradycardia, when the activity of the sinus node is reduced or the conduction of impulses is disturbed, passive ectopic non-sinus rhythms have a substitutive character that excites heart contractions.
