Figure 3 Torsion rate during cardiac cycle. *Significant torsion rate differences between diabetics and control 1 patients during early systole (p < 0.05). #There was a trend toward a higher maximal torsion rate during recoil (TR-r) in diabetics (p = 0.07). %ES = percent systolic duration. Solid squares = control 1 patients (n = 10); open squares = diabetics (n = 16).
