The medical term for an electrical shock delivered to the heart to correct certain abnormal rhythms is defibrillation. Defibrillation is a procedure that uses an electric shock to restore the heart to a normal heart rhythm. It is used to treat ventricular fibrillation and ventricular tachycardia, which are dangerous heart rhythms that can lead to sudden cardiac death. Defibrillation can be done with an external defibrillator, which is a portable device that can be used by trained medical personnel or laypeople, or with an implantable cardioverter-defibrillator (ICD), which is a surgically implanted device that monitors the heart rhythm and delivers a shock if necessary.
