av nodes การใช้

• If so, slowing conduction through the AV node will terminate it.
• Cryoablation is a newer treatment for SVT involving the AV node directly.
• The AV node normally has the second fastest discharge rate.
• The AV node connects the atrial and ventricular chambers.
• The inferior border designates the transverse plane in which the AV node resides.
• The conduction velocity increases in the atria, but decreases in the AV node.
• The distal portion of the AV node is known as the bundle of His.
• The impairment is usually below the AV node.
• The fast pathway is usually located just superior and posterior to the AV node.
• Ventricular pacemaker cells discharge at a slower rate than the SA or AV node.
• Another important property of the AV node is that it slows down individual electrical impulses.
• SVTs can be classified by whether the AV node is involved in maintaining the rhythm.
• Automaticity is also increased in the atria, AV node, Purkinje fibers, and ventricles.
• The cardiac conduction system ( and AV node part of it ) coordinates myocyte mechanical activity.
• In normal individuals, the AV node slows the conduction of electrical impulse through the heart.
• Retrograde P waves refers to the depolarization from the AV node back towards the SA node.
• Class II agents are beta blockers which inhibit SA and AV node depolarization and slow heart rate.
• In first-degree heart block, the diseased AV node conducts the electrical activity more slowly.
• Action potentials from the AV node travel through the bundle of His and thence to the Purkinje fibers.
• This is different from an AV block, which occurs in the AV node and delays ventricular depolarization.
