If you’re suffering from any cardiac disorder or if you want to avoid any unpleasant situation when cardiac arrest happens you need to keep an AED. Many online and in-line stores offer AEDs like Defibtech, AED plus or they also offer different AED packages as well such as AED for school, AED for business, etc. There are different kinds of heart disorders. Supraventricular tachycardia is one of them.
Two parts of the heart, The atria and ventricles work together, alternately contracting and relaxing to pump blood through your heart. The electrical system of our heart is the power source that makes this possible.
SA Node (Sinoatrial Node) :
The impulse starts in a small bundle of specialized cells located in the right atrium. The electrical activity spreads through the atria and causes them to contract. This forces blood into the ventricles. The SA node sets the rate and rhythm of your heartbeat.
AV Node (Atrioventricular Node):
It is a cluster of cells in the center of the heart between the atria and ventricles and acts like a gate that slows the electrical signal before it enters the ventricles. This helps to delay gives the atria time to contract before the ventricles do.
This is the pathway of fibers that sends the impulse to the muscular walls of the ventricles and causes them to contract. This forces blood out of the heart to the lungs and body.
The SA node fires another impulse and the cycle begins again.
This is how our heart beats.
