Implantable Cardioverter Defibrillator (ICD) Combo Device Implant


An ICD is a device implanted inside the body of the person whose heart is beating at an abnormal pace, which cause them to faint, experience sudden cardiac arrest or have other life threatening heart related issues. In some cases, medicines can help stable the heart rate and reduce the risk of fatality, but when medicines do not work, doctors use the method of ICD implant.

ICD is used to help patients take their heart rate back to normal who are suffering from ventricular tachycardia, ventricular fibrillation and cardiac arrest. It is a first line treatment for such diseases after current devices detect the abnormal heart rhythm. ICD is made up of a pulse generator that includes electronic circuits and battery and several leads, which is passed through the skin above the waistline and the leads are inserted into the heart.

The benefit of having an ICD implant is as it is not an open heart surgery, it can be performed while you are asleep and can be done in a couple of hours. After the ICD are inserted, the leads observe your heart rate for abnormalities and detect fibrillation or ventricular tachycardia. If found, the ICD then provides a shock to the heart, which restores the rhythm to usual pace.
