Does an aed monitor a patients heart rhythm?

Yes, an AED (Automated External Defibrillator) monitors a patient's heart rhythm to determine if a shock is necessary. It analyzes the heart's electrical activity and can identify life-threatening arrhythmias, such as ventricular fibrillation or pulseless ventricular tachycardia. If a shockable rhythm is detected, the AED will prompt the user to deliver a shock. If the rhythm is not shockable, it will guide the user in providing CPR instead.
