title: Total cardiac denervation in diabetic autonomic neuropathy.
abstract: Total loss of the autonomic regulation of heart rate is described in a 28-year-old diabetic with extensive autonomic neuropathy. The patient had an almost fixed heart rate that barely responded to any of the tests that stimulate or inhibit the autonomic nerves. Its behavior was similar to that of the transplanted heart.
