[A nasopharynx electrode for BERA potential derivation].
A harpoon-shaped electrode was positioned to the nasopharynx through the nose for registration of BERA-potentials. The amplitudes of peak IV and V increase without changes of latencies. Potential IV is clearer for evaluation of the central conduction time in cases with a single IV/V-complex. Mechanisms of amplitude pattern changes are discussed.
