Heart Rhythm Disorders We Treat

Our consultants have the expertise to care for common and complex arrhythmias, including:

We also treat inherited heart rhythm diseases, including:

Heart Rhythm Disorder Diagnosis

Our consultants use the latest technology to assess and diagnose heart rhythm problems, including 3D electro-anatomical mapping. We create highly detailed maps of your heart to pinpoint the exact source of the arrhythmia, enabling us to provide more accurate, effective treatment. We also offer advanced non-invasive diagnostic services for rapid diagnosis, including cardiac monitoring devices that employ artificial intelligence. Learn more about our heart imaging services.

Heart Rhythm Disorder Treatment

We’re committed to bringing you the newest, most effective innovations in arrhythmia care. Our cardiologists specialise in the latest pacing devices and minimally invasive treatments.

Catheter heart ablation

We use minimally invasive, catheter-based techniques for radiofrequency ablation (extreme heat) and cryoablation (extreme cold) to treat many heart rhythm disorders. Cardiologists create small areas of scar tissue on your heart, disrupting the abnormal electrical impulses that cause irregular heartbeats.

Ablation can reduce or eliminate arrhythmias without the need for major heart surgery. Our team specialises in catheter ablation for ventricular tachycardia, which can reduce the frequency of ICD shocks and improve your quality of life.

Leadless pacemaker implantation and management

Pacemakers are implanted devices that help control an abnormal heart rhythm. We may recommend a pacemaker if you have a slow heartbeat or atrial fibrillation. Our experts excel in leadless pacemaker implantation. Leadless pacemakers are about 90% smaller than traditional pacemakers and don’t have wires (leads).

We implant these self-contained devices directly in your heart with the aid of a catheter inserted into a vein in your groin. This minimally invasive approach means you won’t have an incision or scar on your chest. Leadless pacemakers aren’t visible under the skin, and they eliminate the potential complications associated with leads.

ICD implantation and management

An implantable cardioverter defibrillator (ICD) monitors and corrects irregular heartbeats. It delivers an electrical shock to the heart when the heart’s rhythm becomes dangerous. An ICD can help prevent sudden cardiac death in people with ventricular arrhythmia or heart failure.

At Cleveland Clinic London, we specialise in subcutaneous ICD (S-ICD) implantation. A traditional ICD has leads that go through veins directly into your heart. But an S-ICD has leads that go under your skin and don’t attach to your heart. It’s a less invasive procedure, and S-ICD leads are much easier to remove.

Cardiac resynchronisation therapy

We may recommend cardiac resynchronisation therapy (CRT) if you have heart failure. This treatment helps the bottom chambers of your heart (ventricles) pump blood more efficiently. Our cardiologists can implant a biventricular pacemaker for CRT, which regulates both ventricles of your heart. If you’re at high risk of sudden cardiac death, we may suggest a device that also has a built-in ICD.

Lead extraction

Lead extraction is surgery to remove the leads from a pacemaker or ICD. You may need lead extraction due to an infection, lead damage or lead dislodgement (moved out of place). It’s a highly complex procedure that carries significant risks. If you need lead extraction, it’s essential to select a specialist with extensive experience performing this procedure.

At Cleveland Clinic London, a team of heart surgeons and electrophysiologists works together to perform lead extraction. Our hybrid catheterisation lab uses the most sophisticated imaging and surgical equipment. If necessary, we can transfer patients directly to our dedicated cardiac surgery operating theatre or our 29-bed, level 3 intensive care unit (ICU).
