QTc lacks utility as autonomic neuropathy marker in type 1 diabetes; hypothesis-generating and should not yet change practice.
Does the corrected QT interval correlate with cardiovascular autonomic tests and pupillometry in type I diabetic patients with peripheral neuropathy?
The corrected QT interval is not a reliable indicator of the severity of diabetic autonomic neuropathy and should not be used for its diagnosis.
Bravenboer et al. (1993) studied this question.
