Electrode — ECG/EKG Terminology

Definition: A small adhesive patch placed on the patient's skin that detects the heart's electrical activity and transmits the signal to the monitor.

Key Facts

• Sticky pads with conductive gel
• Placed at specific positions on the chest and limbs
• Connect to the monitor via wires
• Position and skin contact directly affect signal quality

ECG Connection: Electrode placement determines which electrical signals are detected; poor contact causes weak or missing signals.

Why It Matters: Poor electrode contact is the #1 cause of false alarms you'll troubleshoot.
