ECG Interpretation Software: What It Can and Cannot Do
Most modern ECG machines print an automated interpretation. It is a helpful assistant, but it does not replace a clinician.
What it does well
- Measures heart rate, PR, QRS, QT/QTc and axis consistently.
- Flags common patterns quickly.
- Supports triage in busy settings.
Where it struggles
- Arrhythmias. Atrial fibrillation with artifact, flutter and complex rhythms.
- Paced rhythms.
- Noisy tracings. Artifacts can produce false statements.
- Subtle ischaemia. Clinical context is critical.
- Lead reversal. May be misread as pathology.
Best practice
- Record a high-quality tracing. See how to record a 12-lead ECG.
- Read the ECG yourself first, then compare with the machine statement.
- Correlate with symptoms and history.
- Compare with previous ECGs.
- Seek expert review when uncertain.
Equipment
The Maestros 12 Channel ECG and ECGSmart-3 provide interpretation and arrhythmia detection as decision support.
