What is the difference between an electrode and a lead of ECG?
Technically, these are two different things.
- The electrode is the interface with the patient, that sticky pad with the conductive gel, to which you attach the lead, or wire. Each lead is designed to attach at a particular place, and is labeled to indicate that placement.
- Some confusion occurs because all of the literature refers to proper lead placement, which is critical for an accurate EKG, while the first step of proper lead placement is proper electrode placement. Proper lead placement requires not only proper electrode placement, but also attachment of the correct lead to each electrode.
So, the lead is the wire, and is the input to the EKG, where each lead signal is charted separately. The electrode is how the lead attaches to the patient.
Our PM6800 patient monitor(//www.chinautech.com/products/pm6800-patient-monitor.html )can meet the requirements of 12 lead electrocardiogram detection.
