Final answer:
Accelerated Ventricular Rhythm is a heart arrhythmia that occurs when ventricles contract at an abnormal rate. It may require medical intervention such as an artificial pacemaker or an external automated defibrillator to restore normal sinus rhythm.
Step-by-step explanation:
Accelerated Ventricular Rhythm is a type of cardiac arrhythmia where the heart's ventricles contract at a rate faster than normal but slower than that of ventricular tachycardia. This rhythm can occur temporarily in healthy individuals or may indicate an underlying heart condition. In the context of normalizing heart rhythm, arrhythmias such as this are significant because they can impact the overall function of the heart.
The electrical signals that usually cause the heart to beat in a regular, synchronized manner are not functioning properly. When these abnormal heart rhythms are chronic, medical intervention, such as an artificial pacemaker or an external automated defibrillator (EAD), may be used to manage the condition and attempt to restore a normal sinus rhythm. A pacemaker sends electrical impulses to the heart to ensure effective blood pumping, while defibrillators can correct more critical rhythm disruptions like ventricular fibrillation by delivering an electrical shock.
