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 ...
The use of cardiac defibrillation started in 1947 - first in an open chest and ten years later through a closed chest with high energy levels. In 1972, cardiac defibrillation with intracardiac electrodes delivering much less energy of as low as 30 joules was established, following the development of portable units delivering high energy levels ...
Similarly, ICD use in primary prevention is to prevent cardiac death in patients who are at risk for sustained ventricular tachycardia or ventricular fibrillation. This population accounts for the bulk of all ICD implants. There are a multitude of guideline indications for ICD use in primary preventions with varying degree of supporting evidence.
Defibrillation is a treatment for life-threatening cardiac arrhythmias, specifically ventricular fibrillation (V-Fib) and non-perfusing ventricular tachycardia (V-Tach). [1] [2] A defibrillator delivers a dose of electric current (often called a counter-shock) to the heart.
Likewise, a 2022 systematic review on exercise-related cardiac arrests supported early intervention of bystander CPR and AED use (for shockable rhythms) as they improve survival outcomes. [ 86 ] If high-quality CPR has not resulted in return of spontaneous circulation and the person's heart rhythm is in asystole , stopping CPR and pronouncing ...
Paul Maurice Zoll (July 15, 1911 – January 5, 1999) [1] was a Jewish [2] American cardiologist and one of the pioneers in the development of the artificial cardiac pacemaker and cardiac defibrillator.
