ECG Electrodes and Accessories: A Selection Guide for Clinics and Practices
- 1 min reading time
The right ECG electrode affects signal quality. Here is how to choose electrodes, gels and accessories for your diagnostics.
ECG electrodes are a small but decisive consumable: they affect signal quality and comfort. A few distinctions help when sourcing.
Single-use or reusable electrodes?
Single-use adhesive electrodes are hygienic and ready to use – ideal for resting and long-term ECG. Reusable electrodes suit certain devices and applications but require cleaning.
Material and wear time
Consider the intended wear time (short-term monitoring vs long-term), skin tolerance and – for children – suitable smaller electrodes. Foam or tab electrodes cover different needs.
Contact gel and sprays
A good contact medium improves signal transmission. Contact gels and electrode sprays support a low transition resistance and thus a clearer signal.
Skin preparation and compatibility
Clean, dry skin improves lead quality. Also check the compatibility of the electrodes with your ECG devices and connectors.
Frequently Asked Questions
Single-use or reusable – which is better?
Single-use adhesive electrodes are hygienic and practical for routine; reusable ones suit certain devices but need cleaning.
