ECG Electrodes for Electrocardiographical Derivations
ECG electrodes serve to register the electrical voltage changes of the heart, along with heart muscle contractions, and send these signals to the ECG machine. Depending on how they are attached, one can differentiate between the various types of ECG electrodes:
Single-Use Adhesive Electrodes
Adhesive electrodes are disposable electrodes, which are thrown out immediately after use. These hygienic electrodes are especially popular because they are easy to attach and efficiently eliminate the risk of cross-contamination and infectious transmission. On the side attached to the patient, the electrode has an adhesive surface. Often times, there will be a gel application on the electrode, which provides an especially efficient signal transmission. Biotabs ECG electrodes are adhesive electrodes that, contrary to typical adhesive electrodes with push button adaptors, are connected with crocodile or universal pins. Adhesive electrodes are most often used for chest cavity derivations, but can also be used for extremity derivations.
Suction Electrodes Hold via Negative Pressure
Suction electrodes are reusable ECG electrodes that are equipped with a negative pressure generating, rubber ball. This negative pressure ensures that the electrodes securely adhere to the patients' skin. Suction electrodes are used for chest cavity derivations, and the signal quality is improved with the use of contact mediums i.e. ECG gel or electrode cream.
Clip Electrodes for Extremity Derivations
Clip electrodes are exclusively used for derivation of extremities. The reuseable ECG electrodes are clipped to the wrists or ankles and connected with a banana plug or button adaptor. Exactly as with suction and adhesive electrodes, clip electrodes are available in different sizes for adults and children.
A Wide Range of ECG Electrodes & Electrode Belts
One particular highlight in the ECG Electrodes category is the Tapuz universal electrode belt, which covers all 6 precordial leads and can be fixed within seconds via 2 elastic arm bands. This ECG electrode belt can also be applied to hairy patients, without needing to shave them.
