ECG electrodes

ECG Electrodes – All Applications

ECG electrodes play a crucial role in the quality of the electrocardiographic recording. They ensure the transmission of the electrical signal between the patient’s skin surface and the electrocardiograph. An unsuitable, poorly positioned or substandard electrode can generate artefacts, background noise or signal loss, compromising clinical interpretation. CardioDépôt offers a comprehensive range of professional ECG electrodes covering all medical applications: resting ECG, Holter ECG, monitoring, continuous surveillance and stress testing.

Types of electrodes according to clinical use

There are different types of ECG electrodes designed to meet specific examination requirements. Resting electrodes are optimised for short, stable recordings. Holter electrodes are designed for prolonged adhesion and mechanical durability over 24 hours or more. Monitoring electrodes are designed for continuous monitoring in a hospital setting, whilst those used for stress tests are resistant to movement, perspiration and high mechanical stress. The choice of electrode determines the reliability of the signal and the patient’s comfort.

Disposable and reusable electrodes: selection criteria

Disposable ECG electrodes made from conductive hydrogel offer a hygienic solution that is quick to apply and suitable for standard examinations in a doctor’s surgery or healthcare facility. They are available in snap-on, clip-on or clamp versions depending on the cables used. Reusable ECG electrodes, such as limb clamps and suction cups, provide a sustainable alternative for high-volume settings, provided a rigorous cleaning and disinfection protocol is followed. CardioDépôt stocks electrodes from manufacturers recognised for their clinical reliability and consistent manufacturing standards, including 3M, Ambu, Comepa and Skintact.
