Electrocardiograph (ECG machine)
An electrocardiograph records the electrical activity of the heart through electrodes on the skin and prints or stores the tracing for interpretation. It is used in clinics, emergency departments, cardiology units, wards and health check centres.
Common types
- Single channel ECG: a basic unit printing one lead at a time.
- 3 or 6 channel ECG: prints several leads together for faster recording.
- 12 channel ECG: records all 12 leads at once, the hospital standard.
- Holter recorder: a small wearable unit recording ECG for 24 hours or longer.
- Stress test system: ECG with treadmill or bicycle for exercise testing.

Documents to ask for
Buyers ask for CE marking under the EU MDR or US FDA clearance, destination country registration, ISO 13485 for the maker and IEC 60601-1 with IEC 60601-2-25 test reports, and IEC 60601-2-47 for Holter recorders.
Certificates and registrations belong to the product and its manufacturer. We check them with you against the rules of your market before any order.
Is the automatic interpretation reliable enough to replace a doctor's reading?
Automatic interpretation is a support tool and is labelled as such. A clinician should review the tracing, so ask the maker which algorithm is used and for its published validation.
