Assessment of the cardiovascular and gastrointestinal autonomic complications of diabetes

Figure 1 A highly schematic summary of the proposed indirect mechanisms of neuropathy. DAG: Diacylglycerol.

Figure 2 A summary of the autonomic testing options. SDNN: Standard deviation of normal-to-normal; ECG: Electrocardiogram; HF: High frequency; LF: Low frequency.

Figure 3 A typical tracing from a wireless motility capsule recording with time along the X-axis, pressure on the y1-axis (red line) and pH on the y2-axis (green line) and temperature (blue line). Gastric emptying time (GET), small bowel transit time (SBTT) and colonic transit time (CTT) are illustrated. Whole gut transit time is derived from the addition of GET, SBTT and CTT.
