Electrocardiogram (ECG), trendgram of RR intervals and power spectrograms in a control Wistar (vehicle) rat and an STZ-DM rat. Representative ECG records for 1.6s in a control rat (A) and in an STZ-DM rat (B). The trendgram of RR intervals for 10min was obtained from a control (C) and an STZ-DM rat (D). Power spectra of heart rate (RR interval) fluctuations in (E) and (F) were deduced from trendgrams in (C) and (D), respectively.

Daily recordings of heart rate (HR) obtained during the control condition (before STZ injection) and after STZ-injection (A), and histograms of averaged heart rate (HR) during control and DM periods for every 20days (B), obtained from (A). The figure also shows the results of daily analyses of total power (C), HF power (E), and L/H power ratio (G). Histograms of their 20-day average (D), (F), and (H) were respectively obtained from (C), (E) and (G). Arrows indicate the day of STZ injection. **p<0.01, #p<0.001 vs. control group (n=6).

Electron microscopic structures of sympathetic (A, C, E) and parasympathetic nerve endings (B, D, F) closely located to the SA nodal cells. Panels A and B were from a control rat; C, and D were from an STZ-treated rat at week 4; E and F were from an STZ-treated rat at month 4. a for adrenergic nerve endings containing cored vesicles. c for cholinergic nerve endings containing clear vesicles. 22,000×.
