  • In an electrocardiogram (ECG, or EKG), the beginning of ventricular systole is marked by the deflections of the QRS complex. (britannica.com)
  • In an intriguing connection to global geometric phenomena, it turns out that the Fubini-Study metric can be characterized as the boundary case of equality in Gromov's inequality for complex projective space, involving an area quantity called the 2-systole, pointing to a possible connection to quantum mechanical phenomena.

  • subjects
  • a)-g) Paired MBF plots for seven subjects comparing MBF obtained from gated and the self-gated systole dataset. (nih.gov)
  • Another way to look at the data is in Figure 7, which shows a paired MBF plot between the 18 MBF values (3 slices × 6 regions per slice) estimated using gated and the 18 MBF values estimated using self-gated systole for each of the seven subjects. (nih.gov)
