Quizplus · Accepted Answer

Third-degree AV block, also known as complete heart block, occurs when there is complete dissociation between the atria and ventricles, resulting in no atrial impulses being conducted to the ventricles. This causes a slow and unreliable ventricular rate, which can lead to hemodynamic instability and cardiac arrest. Patients with third-degree AV block may be unconscious and require immediate medical intervention, such as placement of a temporary pacemaker or emergency cardiac resuscitation.
