Abstract

Instantaneous heart rate (IHR) was recorded from both controls and patients with insulin-dependent diabetes (IDDM). Spectral analysis showed that change in low/high frequency (LF/HF) ratio upon tilt was reduced in IDDM patients (n.s.) compared to controls (p<0.01). Fractal dimension analysis showed that fractal dimension from IHR recorded supine was significantly lower for IDDM patients with a reduced change in LF/HF upon tilt (p<0.01). Results suggest that the fractal dimension of the resting HR, an index of complexity for cardiovascular control, may be a simple diagnostic of autonomic neuropathy
