[Value of high-frequency stimulation ABR in the diagnosis and treatment of posterior circulation ischemia].
To investigate the value of high-frequency stimulation ABR in the diagnosis and treatment of posterior circulation ischemia. Twenty-three patients complaining vertigo diagnosed by neurologist were selected to accept the examination of high-frequency stimulation ABR. After two weeks of treatment, they were tested again. At the same time,20 healthy persons were chosen as control group. The data were analyzed. The patients had longer ABR latency and wave interval than the normal controls, and the results improved after the proper treatment. High-frequency stimulation ABR can be used to facilitate the diagnosis and to evaluate the therapeutic effect of posterior circulation ischemia.
