What is CRT?
Cardiac Resynchronisation Therapy CRT is a common procedure to improve the heart’s ability to pump blood normally. It is of benefit to people with symptoms of heart failure (such as breathlessness with daily activities and ankle swelling), and evidence of cardiac dyssynchronisation indicated by electrical delay in the heart.
The key to CRT is implanting a device in your chest known as a biventricular pacemaker. It may be a pacemaker only or a defibrillator and a pacemaker depending on your requirements. In about two thirds of cases, CRT improves heart function but it is not possible to predict beforehand who will benefit the most.
Depending your diagnosis, CRT treatment can take one of two forms:
- CRT with a pacemaker
- CRT with a pacemaker and an implantable cardioverter-defibrillator (ICD)
The decision to implant these devices will be made by your cardiologist in consultation with you.
