Why the study?
Does the QT variability index (QTVI) correlate with the severity of cardiovascular autonomic neuropathy in diabetic patients?
Does the QT variability index (QTVI) correlate with the severity of cardiovascular autonomic neuropathy in diabetic patients?
The QT variability index (QTVI) increases with the severity of cardiovascular autonomic neuropathy in diabetic patients, suggesting its potential utility as a marker for early detection and disease progression.
