Recurring concern

Unreliable ECG use and interpretation for clinical decisions

Pin Get email alerts Request correction

First reported 13 Mar 2015•Latest report 5 Jun 2026

Definition

What this concern includes

Includes failures in the dedicated ECG clinical-use process, including deciding when an ECG is indicated, performing or obtaining it, interpreting automated or clinician readings, ensuring staff competence, auditing interpretation and arranging specialist review of abnormal traces.

Not included

  • Excludes general cardiac assessment, diagnostic testing or clinical-decision failures where ECG use or interpretation is not the material unsafe condition.
  • Excludes failures in treatment or observation after an ECG has been reliably obtained, interpreted and appropriately escalated.
  • Excludes generic training, staffing, documentation or communication deficiencies unless they directly impair ECG use, interpretation or specialist review.
  • Excludes failures involving other cardiac electrical recordings unless the assertion explicitly supports the same ECG process.
  • Do not duplicate the existing narrower registry concern focused solely on unreliable interpretation of cardiac electrical recordings when the assertion does not also concern ECG indication, acquisition, competence, audit or escalation.

    Report summary

    Prabhabi Cangi died in Harefield Hospital on 12 August 2025 after an ST elevation myocardial infarction, following an ambulance attendance at her home where she had chest pain, breathlessness and an abnormal ECG. The principal concerns were the lack of a clear pathway for specialist interpretation of abnormal ECGs when paramedics did not convey patients to hospital, and the failure to ensure that intermittent chest pain, breathlessness and abnormal ECG findings resulted in hospital assessment.

    Lack of a clear pathway for specialist doctor interpretation of ECG traces when paramedics decide not to convey patients to hospital

    Wider context from the report

    “That there is no clear pathway for interpretation of ECG traces to a specialist doctor, when attending paramedics decide, where an ECG trace taken at the scene show abnormal automated interpretations, not to convey a patient to hospital. ”

    Commence a trial transmitting ECGs to Heart Attack Centre clinicians for early interpretation and specialist referral.

    Verbatim wording from the response

    “In addition, clinicians have access to real-time clinical support. This includes the LAS Clinical Hub, which is staffed by experienced Clinical Support Managers, and an on-call clinical advice line involving senior paramedics and doctors where escalation is required. In the latter part of this year, the LAS is due to commence a trial of ECG transmission to HAC clinicians for assistance with interpretation. This will facilitate early cardiology review and admission to specialist units as required.”

    Review ECG transmission pilot results and use the findings to inform future pan-London ECG transmission approaches.

    Verbatim wording from the response

    “Notwithstanding this, LAS will reinforce guidance relating to intermittent symptoms and potential ACS scenarios; re-emphasise best practice regarding provision of ECG copies and patient advice; and strengthen messaging regarding the clarity and quality of ECG image capture pending implementation of enhanced digital solutions. Furthermore, an interim review of results from ECG transmission to cardiologists is planned once the pilot phase of this programme of work is complete. This will be used to guide and inform future approaches to ECG transmission pan London.”

    This summary was generated using AI from the published report. Please read the original report for the complete account.

    Report summary

    Mr Gibson was found dead at home on 7 June 2023, with the death attributed to sudden cardiac death due to idiopathic myocardial fibrosis. Eleven days earlier, two ECGs were not recognised as showing complete heart block, and he was discharged from hospital. Concerns included inadequate communication and contextual review of test results, lack of senior review when findings were unexpected, insufficient auditing of ECG interpretation and discharge summaries, and the absence of authoritative national guidance on ECG use and interpretation.

    Lack of authoritative national guidelines for ECG use and interpretation across clinical settings

    Wider context from the report

    “1. The court heard evidence that ECGs are used by different professional groups in a wide range of clinical settings. A consultant cardiologist in this case gave evidence that complete heart block was sometimes a wholly incidental finding on ECG, with the patient not previously exhibiting any obvious signs or symptoms. In the present case, the court heard evidence that the computer-generated interpretations of two ECGs were both incorrect, and that three different (relatively experienced) doctors misinterpreted the ECGs. In those circumstances, I am concerned there are currently no authoritative national guidelines (such as those which exist for CTGs) in place as to the use and interpretation of ECGs in various clinical settings. ”

    Conduct the second phase of the ECG process audit to assess the impact of revised documentation and education.

    Verbatim wording from the response

    “However, it was agreed that there would be benefit in performing an audit to ensure that the correct processes are being followed in ED with regard to the Standard Operating Procedure (SOP), i.e. ECG reviewed by the appropriately qualified member of staff with interpretation and action plan documented. This audit used data from timepoints in December 2023 with 64% of ECGs having an interpretation documented within the medical records. Of those not interpreted within the ED, some patients had opted to leave the department, and some had been under the care of specialties so not the direct responsibility of ED teams. Since that audit we have revised the SOP around documenting standards and delivered education on which patients should receive an ECG. The second phase of the audit will now take place to assess the impact of that intervention.”

    A random audit of selected ECGs is considered unable to provide assurance about interpretation quality.

    Verbatim wording from the response

    “5. As stated above, it is well documented that ECG interpretation accuracy varies between 42% and 75% (expert cardiologists) and so it has been agreed by the Clinical Head of Division and the WTWA Associate Medical Director for Quality and Patient Safety that performing a random audit of selected ECGs would not provide assurance of the quality of interpretation. The only way to seek assurance would be to audit all ECGs and this would be extremely onerous on the ED department and distract from delivery of patient care. An audit presented in August 2024 has shown that we perform 100–190 ECGs every day in ED which amounts to 41% of all attendees. Of these ECGs, 35–56% of them have an abnormality detected.”

    Report summary

    Rex Brook Hall died at Solihull Hospital on 28 July 2016 after presenting with right arm pain and atrial fibrillation and subsequently suffering a myocardial infarction and cardiac arrest. Paramedic ECGs showed ST elevation, but this was not recognised or reviewed on arrival at hospital. The principal concern was possible deficiencies in paramedic foundation training, including ECG interpretation, recognition of arm pain as an atypical sign of myocardial infarction, and identification of ST elevation.

    Wider context from the report

    “That there may be deficiencies in the foundation training of paramedics: 1. one of the paramedics who qualified in 2015 after a 2 year foundation degree gave evidence that he had never had any formal testing on interpretation of 12 lead ECG; 2. the same paramedic gave evidence that he was not aware from his training that arm pain is a recognised, albeit, atypical sign of myocardial infarction; and 3. two paramedics did not identify obvious ST elevation (the other paramedic completed a diploma in paramedic science in August 2012). ”

    Report summary

    Philip Robinson developed vomiting, breathlessness, coughing up blood and pain before being assessed at Bassetlaw Hospital, discharged, and later readmitted in cardiac arrest. The inquest concluded that he died from an acute myocardial infarction with severe coronary artery disease, after the significance of his clinical condition was not appreciated by the treating team. Concerns included inadequate escalation and recording of Early Warning Scores, unclear guidance on ECG use, an extreme risk arising from the absence of senior medical review, and incomplete implementation of systems intended to improve monitoring.
