What to Do After an AI ECG Risk Flag

Receiving an AI ECG alert such as "high risk of structural heart disease" should not be taken as a confirmed diagnosis, nor should it be completely ignored because you have no symptoms for the time being. A more prudent approach is to keep complete records, have the results interpreted by clinical professionals familiar with ECGs and your personal medical history, and decide whether further evaluation is needed based on symptoms, previous tests, and risk background.

This article provides general medical education information only and cannot replace a doctor's in-person consultation, diagnosis, or individualized treatment advice. Different algorithms may differ in purpose, applicable population, and validation status. Follow-up arrangements should be based on the actual report, the instructions of the providing institution, and clinical assessment.

First Understand the Nature of the Result: Risk Flag, Assisted Judgment, and Formal Diagnosis Are Not the Same

An AI ECG alert is typically a risk flag identified by an algorithm based on ECG signals. It may be used to draw clinical staff's attention to a potential abnormality, but it does not in itself mean that a definite structural change in the heart has been found.

Structural heart disease is a relatively broad concept that may involve heart valves, myocardium, heart chambers, or other structures. Whether such a problem exists usually cannot be determined solely from an algorithmic alert. Doctors need to combine the original ECG, symptoms, physical examination, previous data, and select other tests when necessary.

First, confirm the wording in the report:

• Is it "high risk," "elevated possibility," or "recommended further evaluation"?

• Which disease or group of diseases does the alert target, rather than broadly interpreting it as all heart diseases.

• Does the report indicate applicable conditions, limitations, quality issues, or the need for manual review?

• Is there already a physician-signed ECG conclusion, and is that conclusion consistent with the AI alert?

Even if the AI alert is high risk, false positives can occur; even without a risk alert, structural heart disease cannot be ruled out. Results need to be interpreted within the complete clinical context.

Save the Original ECG, Algorithm Alert, Test Date, and Providing Institution

When reviewing, a one-sentence conclusion in a phone screenshot is often insufficient. Try to save or obtain complete records, including:

• The original ECG waveform and complete report, not just the AI summary.

• The original text of the algorithm alert, risk classification, and report version.

• The test date, location, and providing institution.

• Whether there were chest discomfort, palpitations, shortness of breath, dizziness, or syncope at the time.

• Whether the test was done during fever, pain, emotional stress, or after exercise.

• Conditions such as electrode detachment, body movement, or poor signal quality that may affect the recording.

If the ECG comes from a wearable device, portable device, or health screening setting, also state the device type and recording method. Do not crop the waveform yourself, and do not just paraphrase "the machine says there is a problem." Complete information helps manual review of recording quality and reduces duplicate tests and information errors.

Ask What the Model Analyzed and Which Population the Results Apply To

Different AI ECG tools may analyze different leads, recording durations, and risk targets. Asking the institution that provided the results the following questions can help understand the limitations of the alert:

• Does the model analyze a standard 12-lead ECG, a single-lead, or another form of recording?

• What is the specific target it screens for?

• Is the result an aid to clinical judgment, a screening alert, or a formal report already reviewed by professionals?

• In which population has the model been validated, and are your age, underlying conditions, and testing scenario similar?

• What risk stratification does the "high risk" in the report use, and does it give a recommendation on how soon to review?

• Could recording quality, pacemaker, previous arrhythmias, or other conditions affect the algorithm's interpretation?

If the institution cannot explain the purpose or applicable scope of the model, treat the result with more caution. Accuracy rates in news or overall performance in promotional materials cannot be directly converted into the probability of an individual having the disease.

Organize Current Symptoms, Previous Cardiac Tests, Family History, and Complete Medication List

A doctor's judgment of an AI alert often depends on whether it corroborates other information. Before the visit, prepare a concise record:

• Current symptoms: when they started, how long they last, whether they recur, whether they worsen with activity, and whether they are accompanied by chest discomfort, shortness of breath, palpitations, fatigue, dizziness, or syncope.

• Previous tests: previous ECGs, echocardiograms, Holter monitors, imaging studies, and related lab results.

• Past conditions: known hypertension, coronary artery disease, arrhythmias, valve problems, or other significant diseases.

• Family history: whether close relatives have had confirmed cardiomyopathy, serious arrhythmias, premature cardiovascular events, or unexplained sudden death.

• Complete medications: prescription drugs, over-the-counter drugs, supplements, and recently discontinued or adjusted medications.

Do not stop, add, or change medication dosage on your own because of an AI alert. Some medication adjustments can be risky; whether treatment needs to be changed should be decided by professionals familiar with your condition.

Review Pathway Map: Who Interprets the Alert, Whether Further Assessment Is Needed, Who Receives Follow-up Results

Follow-up arrangements can be divided into three consecutive nodes.

The first step is to identify the person responsible for interpretation. Contact the institution that ordered the test, a family doctor, general practitioner, cardiologist, or other professional responsible for your current medical issues, and clarify who will review the original ECG and interpret the AI alert. If the report was generated by a health screening institution or remote platform, ask whether manual review has been done and how to obtain a formal opinion.

The second step is to decide whether further evaluation is needed. The doctor may first review the history and ECG, or consider physical examination or other tests based on the specific situation. Whether echocardiography, ambulatory monitoring, or other assessments are needed depends on the target of the alert, symptoms, and previous data, and cannot be uniformly determined by the AI label alone.

The third step is to ensure a closed loop for results. Before ending the appointment or communication, confirm:

• Who is responsible for reviewing follow-up results.

• How notifications will be sent.

• How long to wait before proactively contacting if no message is received.

• Which new symptoms warrant an earlier visit.

• The time for the next follow-up or re-examination.

If referrals are made between different institutions, keep referral information, report transmission records, and contact persons to avoid a gap where "tests are done but no one interprets them."

Which Ongoing Chest Discomfort, Significant Shortness of Breath, or Syncope Cannot Wait for Algorithm Review

AI review is for result interpretation, not for delaying treatment of ongoing emergencies. If you experience persistent or significantly worsening chest pain, pressure, or tightness; severe or sudden shortness of breath; syncope or near-syncope; discomfort accompanied by cold sweats, extreme weakness, or altered consciousness, contact local emergency services promptly or receive immediate emergency medical evaluation.

Symptoms that are milder but recurrent, occur with activity, or coexist with palpitations, dizziness, or marked decrease in exercise tolerance should also be promptly evaluated by medical professionals. Do not delay emergency treatment while waiting for platform replies, online review, or the next routine appointment, and do not drive yourself to the emergency department.

Risk level cannot be determined solely by whether the AI alert is "high risk." Ongoing symptoms and their severity take priority over waiting for algorithm interpretation.

Verification Boundaries: Accuracy News and a Single AI Alert Cannot Confirm or Exclude Structural Heart Disease

When evaluating AI tools, do not look at just one accuracy number. Model performance is affected by study population, disease prevalence, equipment, recording quality, threshold settings, and validation scenarios. Even if a metric performs well in a specific study, it does not mean it will have the same effect in all institutions, all populations, or every recording.

For individuals, screening and diagnosis must also be distinguished. Screening tools are usually used to help identify people who need further attention, while formal diagnosis requires comprehensive clinical evidence. A high-risk alert cannot prove disease, and a low-risk or negative alert cannot replace medical evaluation for symptoms and risk factors.

When encountering promotional claims, check:

• Whether the information describes the study population and actual usage scenarios.

• Whether it distinguishes sensitivity, specificity, positive predictive value, and other metrics.

• Whether false positives, false negatives, and external validation are reported.

• Whether the device, algorithm version, and target population currently used are consistent with the relevant evidence.

When this information is incomplete, treat AI results as clues requiring interpretation, not final answers.

Final Action: Bring Original Records for Clinical Interpretation and Record the Next Step

After receiving a high-risk alert, follow these steps in order:

1. First determine whether emergency medical help is needed based on current symptoms.

2. Save the original ECG, complete AI report, test date, and institution information.

3. Organize symptoms, previous tests, family history, and all medications.

4. Contact a clinical professional who can review the original data for manual interpretation.

5. Ask whether further evaluation is needed and the potential impact of not testing or delaying testing.

6. Record the responsible person, expected feedback time, follow-up arrangements, and how to respond if symptoms escalate.

The most valuable use of such an alert is to prompt a clinical verification with records, a responsible person, and a timeline. Do not let the words "high risk" push you into self-diagnosis, nor completely ignore the result because of AI limitations. Giving the original records to professionals and ensuring follow-up results are received and interpreted is the key to completing the review.
