• 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.
