What is the significance of monitoring the victim’s rhythm with an AED?

Monitoring the victim’s rhythm with an AED is crucial because it determines whether a shock is advised based on heart rhythm analysis. The AED analyzes the electrical activity of the heart to identify specific arrhythmias, particularly ventricular fibrillation or pulseless ventricular tachycardia, which are life-threatening conditions that require defibrillation. If the rhythm is not shockable, the AED will indicate that no shock is advised, allowing responders to continue CPR and provide the best chance of survival while waiting for advanced medical help. This decision-making process is vital, as delivering a shock inappropriately can lead to further complications or harm. Therefore, the ability of the AED to analyze and interpret the heart's rhythm directly impacts the effectiveness of the emergency response.
