What occurs when an AED unit detects a heartbeat?

When an Automated External Defibrillator (AED) unit detects a heartbeat, it will not deliver a shock. AEDs are designed to analyze the heart's rhythm and determine if the rhythm is shockable, such as in cases of ventricular fibrillation or pulseless ventricular tachycardia. If a normal heartbeat is detected, the device will not advise a shock but may prompt the user to continue monitoring and potentially perform CPR if indicated. This function is essential to ensure that shocks are only delivered when they are truly necessary, thus maximizing the chances of patient survival without causing further harm.

In contrast, when a shockable rhythm is detected, the AED will instruct the user to deliver a shock. The device also generally advises CPR when no heartbeat or ineffective rhythm is found. Therefore, the correct understanding of an AED's function in relation to detecting a heartbeat is crucial for effective use in emergency situations.
