Key facts
The essentials at a glance.
The symptoms to recognise, when to seek help, which specialist to see, and what treatment usually involves.
-
Problems a pacemaker fixes: blackouts and dizziness from heart block or sinus node disease, and fatigue from a heart too slow to meet demand
-
Seek urgent assessment for blackouts with a slow pulse - untreated high-grade heart block is dangerous
-
Specialist: a consultant electrophysiologist usually leads assessment and treatment
-
Implantation is a 60-90 minute procedure under local anaesthetic, usually day-case or overnight; options include conventional, leadless and conduction-system pacing
Understanding the condition
What it is and what happens next.
What causes it, how it is diagnosed, and the treatment routes available in the UK.
What it is and how it feels
The decision rests on correlation: proving that your symptoms - blackouts, near-blackouts, dizziness, fatigue - coincide with documented slow rhythms or conduction block on monitoring. Pacemakers treat symptomatic bradycardia superbly, but they do not help symptoms that are not rhythm-related, which is why careful diagnosis before implant matters so much.
Diagnosis and treatment routes
Modern devices last 10-15 years, are monitored remotely from home, and barely restrict daily life - most people forget they have one. An electrophysiologist will match the device type to your condition, including newer leadless pacemakers and conduction-system pacing that mimics the heart’s natural wiring where appropriate. In many parts of the UK, routine NHS referrals for this kind of problem currently take 20-45+ weeks, whereas an initial appointment with a private consultant is typically available within around two weeks.
Seeing a specialist
Who to see, and how quickly you can be seen.
The specialist for this condition is usually a consultant electrophysiologist. Your GP can refer you on the NHS, or you can arrange a private consultation directly.
