Key result
Tone-entropy analysis of heart rate variability differentiated stages of cardiac autonomic neuropathy, showing higher tone and lower entropy in definite CAN compared to early CAN and normal subjects.
Why the study?
Does tone-entropy analysis of heart rate variability accurately detect and stage cardiac autonomic neuropathy compared to standard Ewing battery tests?
Observational (n=34)
Does tone-entropy analysis of heart rate variability accurately detect and stage cardiac autonomic neuropathy compared to standard Ewing battery tests?
Tone-entropy analysis of 20-minute ECG recordings is a promising non-invasive method to detect and stage cardiac autonomic neuropathy, potentially overcoming limitations of traditional HRV analyses.

May support non-invasive CAN staging; leaves open prospective validation versus Ewing battery.
Khandoker et al. (2009) conducted an observational in Cardiac autonomic neuropathy (n=34). Tone-entropy (T-E) analysis of heart rate variability vs. Normal subjects was evaluated on Tone (T) and entropy (E) values. Tone-entropy analysis of heart rate variability differentiated stages of cardiac autonomic neuropathy, showing higher tone and lower entropy in definite CAN compared to early CAN and normal subjects.
