Signal-averaged ECG shows no excess ventricular late potentials in Type 1 diabetes; leaves open arrhythmic risk stratification in larger prospective cohorts.
Do patients with insulin-dependent (Type 1) diabetes mellitus have an increased incidence of ventricular late potentials on signal-averaged ECG compared to healthy controls?
Signal-averaged ECG does not demonstrate an increased incidence of ventricular late potentials in Type 1 diabetes patients, regardless of coexisting diabetic neuropathy or prolonged QTc.
Großmann et al. (1997) studied this question.
