Welsh cup electrodes have __________(a) low contact impedance(b) negligible contact impedance(c) high contact impedance(d) zero contact impedanceI have been asked this question in unit test.My enquiry is from Electrodes for ECG topic in portion Bioelectric Signal and Electrodes of Biomedical Instrumentation

Answer»

The correct answer is (c) high contact IMPEDANCE

The explanation: Welsh cup electrodes or suction electrodes is a METALLIC cup shaped ELECTRODE which is used for recording ECG from various positions from the chest. It has a high contact impedance as only the rim of the electrode is in contact with the SKIN. It is COMMONLY used to record the unipolar chest leads.
