Implantable cardioverter defibrillator (ICD)


Specialty of Adult Cardiology

An implantable cardioverter defibrillator (ICD), or internal defibrillator is a device through which is circulated a sharp and high-voltage electric current to stop and reverse arrhythmias. It is indicated in cases of cardiorespiratory stops and in which the heart beats out of control and very quick. Under these conditions, the heart muscle is unable to pump blood into the bloodstream, so it is necessary to stop and control this arrhythmia. ICD implantation to an electrode through veins and placed under the skin generator is implanted. With the emergence of rapid arrhythmia, implantable defibrillator detects and automatically emits a loud and sudden shock, enough to send arrhythmia and heart rate returns to normal power.
