This article is a research for electrical neuropathy of 37 patients who were proven to peripheral neuropathy by the high voltage electrical current. The subjects included 37 male patients between 11 and 53 years of age who were admitted to Hangang Sacred Hospital from February 1991 to August 1995. Most of them were injured by high tension current of 22900 Volt, A.C.. Total body surface area(TBSA) of burn was 16.97% average and the depth was revealed 2nd to 3rd degree of burn. We excluded the pre-existing lower motor-neuron abnormality such as diabetes or alcoholism. The electrodiagnosis was carried out on the median, ulnar, peroneal and tibial nerves.

The results were as follows;

1) The ulnar nerve was the most frequently injured nerves by electrical burn and follows the median, peroneal, tibial nerves.

2) The hand was the most frequent entrance sites of electicity in 89.2% of cases, the feet were the most frequent exit sites of electrical current in 67.6% of cases. And 45.9% of nerve injuries were occurred at exit sites of electricity.

3) The pathway of current flow was classified into several types such as `Cross', `Hemi', `Upper', `X', `Y', `Local' and `Mixed' types. The `Cross' and `Hemi' type were the most common pathways in 24.3%.

4) The `Upper' type and the left hand entrance type injury revealed the highest incidence of the cardiac conduction abnormalities. And the sinus bradycardia was revealed the most common abnormality.

According to the several results, peripheral neuropathy and cardiac complication were closely related to the type of current, the current pathway, the entrance and exit site of electrical injury. These results may be helpful in the early detection of complication which is crucial of the electrical burn patients to return to maximal functional and productive life-style.
