Final answer:
A defibrillator is the emergency equipment used to correct abnormal heart rhythm, particularly during a cardiac emergency like ventricular fibrillation; AEDs, designed for layperson use, are commonly found in public places.
Step-by-step explanation:
The piece of emergency equipment used to return proper heart rhythm is a defibrillator. In the case of a cardiac emergency, such as a heart attack caused by ventricular fibrillation (fast, irregular heartbeats), the defibrillator delivers a significant charge in a short burst. This electrical shock can terminate the arrhythmia and allow the heart's natural pacemaker to restore a normal rhythm. Automated external defibrillators (AEDs) are portable units designed for use by laypersons. They often provide verbal instructions, can automatically diagnose the heart's rhythm, and deliver a shock with the appropriate energy and waveform. Additionally, CPR is frequently recommended before using a defibrillator.
A piece of emergency equipment used to return proper heart rhythm is a defibrillator. A defibrillator is a portable electronic device that delivers a large charge in a short burst, or a shock, to a person's heart to correct abnormal heart rhythm or arrhythmia. It is commonly used in ambulances and can also be found in many public places.
