Question

Which electrodes can work even after being induced to large electric discharge such as defibrillation?

(a) polarizing electrodes

(b) magnetic electrodes

(c) non-polarizing electrodes

(d) electrolytic electrodes

This question was posed to me in a job interview.

I would like to ask this question from Recording Electrodes in portion Bioelectric Signal and Electrodes of Biomedical Instrumentation

Answer 1

The correct option is (c) non-polarizing electrodes

For explanation: Non-polarizing electrodes are designed to rapidly dissipate any charge imbalance induced by powerful electric discharges such as a defibrillation procedure. Rapid depolarization enables the immediate reappearance of bioelectric signals on the monitor after defibrillation. For this reason, non-polarizing electrodes have become the electrodes of choice for monitoring in the intensive care units and stress testing procedures.
