An automated external defibrillator or automatic electronic defibrillator (AED) is a portable electronic device that automatically diagnoses the life-threatening cardiac arrhythmias of ventricular fibrillation (VF) and pulseless ventricular tachycardia, [1] and is able to treat them through defibrillation, the application of electricity which stops the arrhythmia, allowing the heart to re ...
A circuit diagram showing the simplest (non-electronically controlled) defibrillator design, depending on the inductor (damping), producing a Lown, Edmark or Gurvich Waveform. Early successful experiments of successful defibrillation by the discharge of a capacitor performed on animals were reported by N. L. Gurvich and G. S. Yunyev in 1939. [36]
A defibrillator will deliver an electrical current through a pair of electrodes placed on the person's chest. This is thought to depolarize myocardial tissue thereby stopping the arrhythmia. [ 100 ] Defibrillators can deliver energy as monophasic or biphasic waveforms, although biphasic defibrillators are the most common.
Nearly two years ago, NFL fans watched in horror as Buffalo Bills safety Damar Hamlin collapsed on the field after experiencing a sudden cardiac arrest (SCA) midgame. But the now-26-year-old ...
A circuit diagram (or: wiring diagram, electrical diagram, elementary diagram, electronic schematic) is a graphical representation of an electrical circuit. A pictorial circuit diagram uses simple images of components, while a schematic diagram shows the components and interconnections of the circuit using standardized symbolic representations.
Illustration of Implantable Cardioverter Defibrillator (ICD) An implantable cardioverter-defibrillator (ICD) or automated implantable cardioverter defibrillator (AICD) is a device implantable inside the body, able to perform defibrillation, and depending on the type, cardioversion and pacing of the heart.
A new type of internal heart defibrillator, implanted for the first time in Michigan at Sparrow Hospital, could help younger patients live longer.
