Implantable cardioverter defibrillator

Abstract

Defibrillators are devices used for the treatment of sudden cardiac arrest such as ventricular arrhythmia and ventricular fibrillation. Defibrillator gives the particular amount of electrical energy to the heart. This electrical shock regains normal heart rhythm within seconds. Various types of defibrillators are available nowadays. Automated external defibrillator, wearable defibrillator etc. are some types of defibrillators used now. Most advanced technology develops the implantable cardioverter defibrillator. This defibrillators are placed within the body and which are capable to perform the cardio version, defibrillation and pacing of the heart.The implantation process is just like the pacemaker. This is placed in the apex or septum of the right ventricle. Like pacemaker the implantable cardioverter defibrillators have only one wire in the heart. That is, in the right ventricle. The rate of sudden death due to cardiac arrhythmia and other cardiac disorders can be reduced by the implantable cardioverter defibrillator therapy.
