When the aed analyzes the heart rhythm, the instrument will prompt that the patient's heart rate is being analyzed to determine whether he is in a state of ventricular fibrillation, so as to avoid touching the patient and interfering with ECG analysis.
Aed is a portable medical device, which can diagnose specific arrhythmia and give electric shock defibrillation. It can be used by non-professionals to rescue patients with cardiac arrest.
