Cardiology — electrophysiology — NHS waiting times (DM01)
Tests of the heart’s electrical activity and rhythm.
How long are NHS Electrophysiology diagnostic waits?
Cardiology — electrophysiology is one of the 15 key diagnostic tests in NHS England's DM01 collection. Tests of the heart’s electrical activity and rhythm. Arrhythmias and conduction problems that cause palpitations, blackouts or an abnormal heartbeat. The operational standard is that fewer than 1% of patients should wait 6 weeks or more for a DM01 test — not met across diagnostics since November 2013. The current Electrophysiology figure publishes here once it has been extracted from the DM01 file and verified.
What it diagnoses
Arrhythmias and conduction problems that cause palpitations, blackouts or an abnormal heartbeat.
Why the wait matters
A low-volume but clinically important line; delays can postpone the diagnosis of rhythm disorders that raise stroke risk.
Electrophysiology DM01 waiting figure
Figure loads from the DM01 file
The per-test Electrophysiology waiting figure (number and share waiting 6+ weeks) publishes here as soon as it has been extracted from the NHS England DM01 monthly file and checked against the source. Gera does not display a diagnostic number it has not verified — so no figure is shown until then.

Electrophysiology: FAQs
- What is Electrophysiology and what does it diagnose?
- Tests of the heart’s electrical activity and rhythm. Arrhythmias and conduction problems that cause palpitations, blackouts or an abnormal heartbeat.
- What is the NHS waiting-time standard for Electrophysiology?
- Cardiology — electrophysiology is one of the 15 key diagnostic tests in NHS England's DM01 collection. The operational standard for all DM01 tests is that fewer than 1% of patients should wait 6 weeks or more — a standard not met across diagnostics as a whole since November 2013.
- Does a Electrophysiology backlog affect other waits?
- A low-volume but clinically important line; delays can postpone the diagnosis of rhythm disorders that raise stroke risk.
- What is the current Electrophysiology waiting figure?
- The per-test Electrophysiology waiting figure publishes here as soon as it has been extracted from the NHS England DM01 monthly file and checked. Gera does not display a diagnostic number it has not verified against the source, so no figure is shown until then.
Waiting a long time for Electrophysiology?
NHS Electrophysiology waits can run well beyond the 6-week standard. Many people use a private online consultation to discuss symptoms, understand whether an investigation is appropriate, or get a referral while they wait. GeraClinic connects you with a UK-registered doctor by video — a private service, not part of or affiliated with the NHS. For a medical emergency always call 999 or go to A&E.
