Background: The use of linear methods of heart rate variability (HRV) to assess autonomic modulation in subjects with type 1 diabetes mellitus (T1DM) is controversial and studies using non-linear methods are scarce and inconclusive. Aims: To compare the autonomic modulation in young type 1 diabetic and healthy through non-linear methods of HRV (Recurrence plot [RP] and Poincaré plot), associated with indexes obtained by geometrical and linear methods (time domain and frequency). Methods: We analyzed data from 43 young volunteers (20 with T1DM and 23 healthy) of both genders. All subjects underwent a medical history, physical assessment and autonomic evaluation. For analysis of HRV, heart rate was recorded beat to beat , with volunteers in the supine position for 30 minutes , and a stretch of 1000 RR intervals was used to obtain the indexes: recurrence rate (REC) , determinism (DET) and Shanon entropy (SE) derived from RP ; SD1 , SD2 and SD1/SD2 obtained by plot Poincaré; RRtri...
