Cardioversion is a medical procedure by which an abnormally fast heart rate (tachycardia) or other cardiac arrhythmia is converted to a normal rhythm using electricity or drugs. Synchronized electrical cardioversion uses a therapeutic dose of electric current to the heart at a specific moment in the cardiac cycle , restoring the activity of the ...
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.
Defibrillation is often an important step in cardiopulmonary resuscitation (CPR). [6] [7] CPR is an algorithm-based intervention aimed to restore cardiac and pulmonary function. [6] Defibrillation is indicated only in certain types of cardiac dysrhythmias, specifically ventricular fibrillation (VF) and pulseless ventricular tachycardia.
Electric cardioversion (a shock to your heart to restore its rhythm) ... When heart arrest occurs outside of a hospital, the main treatment is a shock with an automatic external defibrillator ...
Bernard Lown (June 7, 1921 – February 16, 2021) was a Lithuanian-American cardiologist and inventor. Lown was the original developer of the direct current defibrillator for cardiac resuscitation, and the cardioverter for correcting rapid disordered heart rhythms.
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 ...
Defibrillation or cardioversion may be accomplished by an implantable cardioverter-defibrillator (ICD). Electrical treatment of arrhythmias also includes cardiac pacing . Temporary pacing may be necessary for reversible causes of very slow heartbeats, or bradycardia (for example, from drug overdose or myocardial infarction ).
Otherwise, immediate cardioversion is recommended, preferably with a biphasic DC shock of 200 joules. [2] In those in cardiac arrest due to ventricular tachycardia, cardiopulmonary resuscitation (CPR) and defibrillation is recommended. [5] Biphasic defibrillation may be better than monophasic. [5]
