Sinus node dysfunction.
The electrical discharge arises in the sinus node.
Examples include sinus node dysfunction and heart block.
Sinus node: a. produces waves of sinus frequency.
Is supported by the highly effective Na+/K+-ATPase in the sinus node cells.
Sinus node dysfunction is treated with a pacemaker.* Heart block.
In a healthy heart, the sinus node functions as the pacemaker.
Is supported by the lower efficacy of the Na+/K+-ATPase in the sinus node cells.
A properly functioning sinus node regulates the rhythm and speed of a person's heart.
Excitation source with this arrhythmia may be in a typical place(sinus node) or move in atrium and ventricle.
They come from the sinus node of muscle fibers, which makes the heart rhythm unchanged.
The heart pumps blood into the body andcontracts due to electrical impulses that form in the sinus node, located in the right atrium.
The sinus node produces electrical impulses, usually starting with each heart beat.
One cause of bradycardia is a disorder of the sinus node, causing electrical impulses that are too slow.
The sinus node, and with it the heart rate, is influenced by the nervous system and certain hormones.
The nervous system and released hormones support the sinus node in the heart and speed up the pumping of blood into the body.
If the sinus node is working properly but the spreading of the signal to the other cardiac cells is impaired, the signal is blocked.
If you have slowheart rate(high degree heart block or sinus node disease), and don't have a pacemaker fitted.
From the sinus node, electrical impulses pass through the atria, cause contractions in the muscles of the atria and the supply of blood to the ventricles.
In normal myocardial tissue,an electrical impulse moves unidirectionally- from the sinus node to the side of the atrioventricular junction.
In some people, the sinus node problems may result in alternating slow and fast heart rates(bradycardia-tachycardia syndrome).
Ivabradine is therefore not recommended in patients with atrial fibrillation orother cardiac arrhythmias that interfere with sinus node function.
Second or third degree atrioventricular(AV) block or sinus node dysfunction, unless these patients have a functioning artificial pacemaker.
If the sinus node is weakened, the atrioventricular will take over its function and begin to transmit impulses to the heart muscle with a frequency of 40-60 contractions per minute.
The active substance in Ivabradine Accord, ivabradine,blocks the‘If current' in the sinus node, the natural‘pacemaker' that regulates the heart rate.
The treatment of atrial fibrillation consists of interrupting the formation of random impulses, synchronizing the cells of the heartand returning function to the main impulse generator, i.e. the sinus node.
An increase in the number of pulses in the sinus node or other parts of the conduction system, respectively, causes an increase in the heart rate- tachycardia.
The main role in theformation of electrical impulses in the heart belongs to the sinus node, from which in the leading ways they diverge to the ventricles and atrium.
The cardiac effects are specific to the sinus node with no effect on intra-atrial, atrioventricular or intraventricular conduction times, nor on myocardial contractility or ventricular repolarisation.
This means that normal physiological excitation occurs automatically in the sinus node and the heart contracts in time with the pulses generated in the sinus node.
