Implantable Cardiac Device Management
Implantable Cardiac Device Management
Implantable cardiac devices are used to regulate the heartbeat, prevent dangerous rhythm disturbances, and support heart function in patients with a range of heart conditions. These include:
- Pacemakers (including leadless pacemakers)
- Implantable cardioverter-defibrillators (ICDs)
- Cardiac resynchronization therapy (CRT) devices
Our care goes beyond implantation. We provide comprehensive, long-term device management, ensuring that each device continues to work effectively over time. This includes:
- Careful selection of the most suitable device for your condition
- Safe and precise implantation by experienced specialists
- Regular follow-up and remote or in-clinic monitoring
- Ongoing device checks, programming, and optimisation
Our goal is to relieve symptoms, prevent complications, and provide long-term protection, helping patients return to daily life with confidence.
What is a pacemaker?
A pacemaker is a small medical device that restores your heartbeat at a normal, steady rate. It is used when the heart beats too slowly, presence of electrical pauses, or has an irregular rhythm.
A pacemaker monitors your heart rhythm continuously. When it detects heartbeat that is too slow or irregular, it sends small electrical signals to stimulate the heart and keep it beating properly.
- Relieves symptoms like dizziness, fatigue, and fainting.
- Helps maintaining a safe heart rate.
- Improves quality of life.
- Prevents complications from slow heartbeat.
What is a leadless pacemaker?
A leadless pacemaker is a small, self-contained device placed directly inside the heart, without the need for wires (leads) or a surgical pocket under the skin. It is significantly smaller than a conventional pacemaker, similar to size of a capsule and is designed to deliver pacing therapy from within the heart itself.
- Delivered through a catheter via a vein, usually through the groin.
- Positioned inside heart chambers.
- Monitors the heart rhythm and delivers pacing when needed.
- Lower risk of infection (no surgical pocket or leads).
- No visible lump or scar on the chest.
- Avoids long-term complications related to pacing wires.
What is cardiac resynchronization therapy (CRT)?
CRT is a specialised pacing therapy for patients with heart failure, where the heart’s lower chambers (ventricles) beat out of sync. This lack of coordination reduces the heart’s efficiency. CRT restores synchrony by delivering timed electrical signals to both sides of the heart, helping it pumps more effectively.
CRT works by using a specialised device with leads placed in both ventricles (and often the right atrium) it delivers precisely timed electrical impulses to coordinate (resynchronise) the contraction of the heart chambers. By restoring synchrony, CRT improves cardiac output and reduces the workload on the heart.
- Improves symptoms such as breathlessness and fatigue.
- Enhances overall quality of life.
- Reduces hospital admissions for heart failure.
- May improve heart function over time.
- Device implantation-related complications.
- Lead placement challenges due to heart anatomy.
What is an Implantable Cardioverter-Defibrillator (ICD)
An ICD is a device designed to detect and treat life-threatening fast heart rhythms, such as ventricular tachycardia or ventricular fibrillation. These rhythms can be life-threatening and may lead to sudden cardiac arrest if untreated.
The ICD continuously monitors your heart rhythm. If a dangerous rhythm is detected, it can:
- Deliver rapid pacing (ATP) to interrupt the abnormal rhythm.
- Deliver a controlled shock to reset the heart back to a normal rhythm.
The response happens immediately, before symptoms become severe.
- Provides continuous, automatic protection.
- Responds quickly to life-threatening rhythms.
- Can significantly reduce the risk of sudden cardiac death.
- Inappropriate shocks (treating non-dangerous rhythms).
- Discomfort from shocks.
- Device-related complications.
What is conduction system pacing (CSP)?
Conduction system pacing (CSP) is an advanced pacing technique that delivers electrical signals directly into the heart’s natural electrical pathways. This allows the heartbeat to follow its normal activation pattern, resulting in a more physiological and coordinated contraction.
Why It Matters
Compared to conventional pacing, CSP may:
- Better preserve heart pumping function.
- Reduce the risk of pacing-related heart failure over time.
- Provide a more natural and efficient heartbeat.
FAQ - Pacemakers
While rare, some patients may experience an allergic reaction to the materials used in the pacemaker. Notify your doctor if you have a history of allergies.
Most insurance plans cover pacemaker implantation, but it’s essential to verify coverage with your provider and hospital.
Modern pacemakers are highly reliable. If a malfunction occurs, it is often detected during routine check-ups and can be addressed promptly.
Yes, pacemakers can be implanted in children with congenital heart block or severe arrhythmias, though the procedure and devices are tailored to their needs.
Yes, pacemakers can be safely removed or replaced, if necessary, due to upgrades or complications.
