Cardiac Rhythm Management (CRM)
Heart rhythm disturbances (arrhythmias) are common.
Our care for patients includes assessment, full diagnostic investigation, medical and procedural treatments, and follow-up in outpatient clinics.
We see and treat thousands of patients each year with the latest technology, caring for the people of Oxfordshire as well as patients from the surrounding counties and further afield including the Channel Islands and Malta.

We usually have two Clinical Fellows and two Research Fellows working in arrhythmia management (senior trainees with an interest in cardiac rhythm management).
Heart rhythm disturbances
Any rhythm other than the normal (or 'sinus') rhythm can be considered a rhythm disturbance (or 'arrhythmia').
An arrhythmia may cause no symptoms, or may result in:
- dizziness
- loss of consciousness
- an awareness of the heartbeat (palpitation)
or other symptoms including:
- fatigue
- shortness of breath
- chest discomfort.
It is extremely helpful to have an ECG at the time of a patient's symptoms, in order to diagnose the underlying heart rhythm and give the most appropriate treatment.
If a patient has symptoms that suggest a slow heart rhythm (or 'bradycardia') a pacemaker may be needed.
There are numerous different kinds of fast heart rhythm disturbance (tachycardia).
A consultation with a member of our team, along with findings of investigations, helps to determine the cause of symptoms related to a fast heartbeat.
Tests
We routinely do a heart tracing or electrocardiogram (ECG) when we see patients in our clinic.
Other tests that may be necessary are:
In some circumstances a cardiac electrophysiology study may be recommended.
Treatments
Some kinds of heart rhythm disturbance do not require treatment and it may be enough to reassure patients that there is no cause for concern.
Sometimes, tablet treatment may be recommended, either as regular medication or using a 'pill in the pocket' (as and when needed) approach.
In some circumstances, a catheter ablation procedure may be recommended.
Implantable Cardioverter Defibrillator (ICD) therapy is usually recommended for patients at risk of sudden death from rapid heart rhythm disturbances. We have the expertise to implant either transvenous or subcutaneous ICDs.
Cardiac Resynchronisation Therapy (CRT) (or 'biventricular pacing') is a pacemaker treatment which aims to recoordinate the heart's pumping function, and is suitable for some patients with heart failure. This can be combined with the functionality of an ICD when appropriate.
