Channel count and print format
A 12-lead ECG is always acquired from ten electrodes; channel count describes how many leads print simultaneously. Three-channel units are compact and economical for clinics with modest volumes; 12-channel units print a full page quickly and suit diagnostic centres and hospitals.
Throughput and consumables
For a centre running high daily volumes, paper handling matters more than most specifications. Compare thermal paper width and format, roll versus z-fold, availability of paper locally and cost per trace. Consumable availability is a recurring operational cost, not a one-time item.
Interpretation and reporting
Automatic measurement and interpretive statements speed reporting but remain advisory; every trace requires clinician confirmation. Check whether the interpretation algorithm covers paediatric criteria if you image children.
Connectivity
PDF export, network transfer and DICOM or HL7 integration determine whether traces reach the patient record automatically. Where records are currently paper, choose a unit that can be connected later rather than one that never can.
Beyond resting ECG
Centres offering cardiac work-ups typically pair resting ECG with treadmill stress testing and Holter monitoring. Sourcing these together keeps reporting software, cable types and consumables consistent.
