  1. Value are means ± SD, IR: insulin resistant offsprings of type 2 diabetic patients, NIR: non insulin resistant offsprings of type 2 diabetic patients, SDNN: standard deviation of all sinus rhytm RR intervals, RMS SD: the square root of the mean of the sum of the squares of differencies between adjacent NN intervals, LF: low frequence, HF: high frequence, hours of Holter registration: night time = 0–6 am, morning = 7–12 am, afternoon = 1–6 pm, evening = 7–11 pm. P Value is between groups.
