The SA node directs electrical impulses to the right section of the heart at the right time.
When an electrical impulse is released from the SA node, it causes the heart's upper chambers to contract.
The sa node acts independently of the brain to generate electricity for the heart to beat.
During rest, the speed of electrical signals originating from the SA node is slow, so the heart beats slowly.
If the SA node fails, other parts of the electrical system can take over, usually at a slower rate.
The AV node picks up the signal sent by the SA node and transmits it through the atrioventricular(AV) bundle.
This electrical signal begins in the sinoatrial node, also called the SA node or the sinus node. .
The SA node generates an electric beat about 60 to 80 times a minute, and each should result in a heartbeat.
There is a slight delay in getting the electrical signal from the SA node to the AV node, but the heart functions normally.
If the SA node should fail, the other parts of the electrical system can take over, although usually at a slower rate.
It can coexist withother supraventricular tachycardias due to the disassociation between the SA node and the AV node. .
In addition to receiving pulses from the SA node, the atria receive electrical signals from nearby sources, such as pulmonary veins.
There can also be delays in transmission of the electrical impulse anywhere in the system,including the SA node, the atria, the AV node, or in the ventricles.
The signal from the SA node is picked up by another mass of conductive tissue known as the atrioventricular(AV) node. .
Beta-blockers: These drugs slow the heart rate by decreasing the rate of the SA node and by slowing conduction through the AV node. .
The signal from the SA node is picked up by another mass of conductive tissue known as the atrioventricular(AV) node. .
Normally, the heart beats in asinus rhythm with each electrical impulse generated by the SA node resulting in a ventricular contraction, or heartbeat.
The SA node, under ordinary circumstances, is the major generator of cardiac impulses as it has the highest rate of spontaneous depolarization(automaticity).
Sick sinus syndrome is a disease wherein the SA node cannot generate signals frequently enough to maintain adequate heart rate.
The SA node sends electrical impulses at a certain rate, but your heart rate may still be altered by physical demands, stress, or other factors.
During normal atrial depolarization,the main electrical vector is directed from the SA node towards the AV node, and spreads from the right atrium to the left atrium.
From the SA node, impulses for contraction travel to the atrioventricular(AV)node, located in the lower interatrial septum.
To maintain conformable blood pressure andto prepare the heart for its next contraction, the SA node constantly prolongs a small amount of tension over all the muscles.
Instead of the SA node generating a single electrical signal, numerous areas of the atrium become irritated and produce electrical impulses.
These medications can alsoaggravate bradycardias in patients with existing diseases of the SA node, AV node, and other parts of the heart's conduction system.
The reason why they normally don't is that the SA node“overrides” them and they accept the impulse from it, instead of trying to create one on their own.
