Implantable Cardioverter Defibrillator

The implantable cardioverter defibrillator (ICD) is a device that can protect you against dangerous abnormal heart rhythms by constantly monitoring your heart rhythm. The ICD is able to detect ventricular tachycardia (VT) or ventricular fibrillation (VF). These two heart rhythms can be life-threatening if they are not treated.


The ICD treats these rhythms by pacing, or shocking, the heart back to a normal rhythm. The ICD can also act as a pacemaker. Your doctor will program your ICD to best fit your specific needs.

ICD Placement

The ICD placement is done in the Electrophysiology (EP) Lab. You will be given sedation to help you relax during the procedure. The procedure lasts several hours. Most patients are able to go home the next morning.
