CRT is a pacemaker that has 3 leads which tries to coordinate the ventricles pumping action. The leads are placed:
- In right atrium
- In right ventricle
- Through coronary sinus and sits on outside of left ventricle
The battery is inserted under the skin on the left side of the chest. This procedure is performed under local anaesthetic and can take approximately 2-3 hours. There can be significant bruising post-insertion due to the insertion of the battery. Patients are advised not to lift their arm above shoulder height for the next 4-6 weeks until the leads are embedded in the hearts tissues.
Once the wires are embedded normal activities can be resumed but contact sports should be avoided.
As part of the procedure, many patients will also have a defibrillator integral to the device (CRT-D). In this case additional information is required. Patients are counselled about shocks and the device can be programmed to the individual needs. It is maintained with regular check-ups. Driving restrictions do apply depending on reason for implantation. Patients should be advised to check DVLA.
