Diagnostic Test & Treatment
Pacemaker & Cardiac Device Implantation
Implantable cardiac devices are small devices placed in the body, usually near the heart, that help to monitor and treat heart rhythm abnormalities and improve heart function. They include pacemakers, defibrillators and resynchronisation devices.
01Why It’s Done
Dr Lee may recommend this for patients with:
- Slow heart rates (treated with a permanent pacemaker)
- Risk of dangerous fast rhythms (treated with an implantable defibrillator, ICD)
- Heart failure (treated with cardiac resynchronisation therapy, CRT)
02How It Works
- The device is implanted under the skin, usually on the left side of the chest, under local anaesthetic.
- One or more fine leads connect the device to the heart (modern leadless and subcutaneous options are also available).
- The device is programmed and tested before you go home.
03Duration, Recovery & What To Expect
Implantation is typically a short procedure. You will receive guidance on arm movement, wound care and device follow-up.
