Complete Heart Block, also known as third-degree AV block, is a serious condition where the electrical signals from the heart's atria do not conduct to the ventricles at all. This results in a disconnection between the heart's upper and lower chambers. The most significant consequence of this condition is the potential for bradycardia, which can lead to inadequate cardiac output and symptoms such as dizziness, fainting, or cardiac arrest.

Because this type of block can severely impair the heart's ability to pump blood effectively, it typically necessitates immediate medical intervention in the form of a pacemaker. A pacemaker is a device that is implanted to take over the job of conducting electrical impulses from the atria to the ventricles, thus restoring normal heart rhythm and ensuring effective cardiac function.

Other treatment options, such as medication adjustment or electrolyte supplementation, may be appropriate in different contexts, but when it comes to complete heart block, the immediate concern is to restore reliable cardiac electrical activity, which is best achieved with a pacemaker. Therefore, the need for prompt medical intervention to install a pacemaker is the definitive treatment for this condition.
