ICD and CRT Implantation

ICD stands for Implantable Cardioverter Defibrillator. It is made up of a small, slim, box-shaped device which contains a battery and electronic circuits. The device is connected to your heart by wires known as leads. The leads are passed along a blood vessel to your heart and the ICD box is usually implanted under the skin in your upper chest, near your collarbone. The ICD can recognize and monitor your heart rhythm and can give you some treatments if needed. It also stores information about your heart rate and rhythm which can be accessed when you come to the clinic for follow-up

What is Cardiac Resynchronisation Therapy?
Cardiac Resynchronisation Therapy (CRT) devices are used to help to treat heart failure and can be either a permanent pacemaker or an ICD. They work by making the heart chambers pump at the same time (synchronously) and improve the overall function of the heart so that you feel less breathless and have more energy.
