Electrodes for Electrocardiographic Derivations
ECG electrodes serve to register the electrical voltage changes of the heart, along with heart muscle contractions, and send their signals to the ECG machine. Depending on how they are attached to the patient, one can differentiate between adhesive electrodes, suction electrodes and clip electrodes.
Single-Use Adhesive Electrodes
The majority of adhesive electrodes are disposable and can be thrown away immediately after use. Generally, they are made of foam or non-woven textile material. The electrode is on the patient side and surrounded by an adhesive surface. The backside is equipped with a button connection to connect the electrode to the ECG machine.
Adhesive electrodes are ideal for ECG monitoring on the chest. Depending on the model, they can be used for resting ECGs, stress ECGs and Holter monitors. Such hygienic electrodes are particularly popular because they are easy to attach and efficiently eliminate the risk of cross-contamination and infectious transmission.
An especially popular product is the non-sterile single-use adhesive electrode from Dalhausen. This disposable medical electrode has a liquid gel application and can be used for long-term monitoring. The adhesive electrode is certified after ISO 10993, providing a biological assessment of the medical product and an assessment of the compatibility of the materials with the body.
The Biotabs Adhesive ECG Electrodes offer a particularly secure hold and can be used with both crocodile and universal clips. The disposable ECG electrodes can be used on extremities and chest leads.
Suction Electrodes Hold via Negative Pressure
Suction electrodes are reusable electrodes that are equipped with a negative pressure generating rubber ball. This negative pressure ensures that the electrodes securely adhere to the patient's skin. Suction electrodes are used for chest cavity derivations, and their signal quality is improved with the use of contact mediums like ECG gel or electrode cream.
In our shop, you will find the Teqler Suction Electrode for children or adults. The blue rubber ball creates a suction effect and the electrode is equipped with a connection for rivet buttons or banana plugs. The signal can additionally be improved by using conductive wet gel or electrode spray.
Clip Electrodes for Extremity Derivation
Clip electrodes are exclusively used for derivation of extremities. The reusable ECG electrodes are clipped to the wrist or ankles and connected with a banana plug or button adapter. Thanks to their large contact surface, the clip electrodes from Teqler are especially suitable for medical application and can be bought in sets of 4 for adults and children.
A Large Selection of EKG Electrodes & Electrode Belts
One particular highlight in the ECG electrodes category is the LevMed AllBrand ECG Electrode Belt, which covers all precordial leads and can be secured within seconds with help of 2 elastic arm brackets. The ECG electrode belt can even be used on hairy patients without the need for shaving.
Electrode Gel, Cream and Spray for Excellent Lead Quality
To bridge the distance between the electrodes and the skin and to improve the lead quality, one can use different kinds of contact media. The most popular solutions are electrode gel, electrode cream and contact spray. When choosing a product, one should always be careful to choose a hypoallergenic product that does not stain.
