Description

TECHNICAL FIELD The disclosure relates to the technical field of medical device, and more specifically, to a medical device with a defibrillator function. BACKGROUND Heart disease, such as Out-of-Hospital Cardiac Arrest (OHCA), is one of leading causes of death in humans. A large proportion of Out-of-Hospital Cardiac Arrests are attributed to ventricular fibrillation or pulseless ventricular tachycardia (VF/VT). If timely defibrillation is available, these patients will have a higher survival rate. Although significant progress has been made in external defibrillation technology, conventional defibrillators only provide single-channel defibrillation, which urgently needs to improve the defibrillation effect for refractory ventricular fibrillation. Refractory ventricular fibrillation refers that a heart rhythm of the patient still remains VF/VT but fails to be converted to a sustained organized rhythm, after multiple (>3) attempts of conventional defibrillation. About 10% of patients with Out-of-Hospital Cardiac Arrest of ventricular fibrillation suffer from refractory ventricular fibrillation, while conventional single-channel defibrillation technology has difficulty in restoring organized rhythm for such patients in a timely manner.
