Abstract
We have applied the vector field phase gradient mapping method(VFPGM) by using this novel method to healthy human subject and we obtain the following results: 1 ) The spatial distribution with regard to the wave form or the instantaneous phase of specific frequency component is shown at every 1.8 ms and then we analyze all of this data by using our PGMM. 2 ) We demonstrate that dynamics of the singular points on a vector field of cardiac phase measured by the phase tracking method in ultrasonic measurement were successfully applied by the Bekki-Nozaki hole solution of the CGLE since a phase defect on vector filed generates the hole dynamics.
In cardiac interventricular septum, three type of simple instabilities of a spatially universal steady state are responsible for a variety of patterns which can be classified as follows: (1) SPOC in time and space, (2) absolute and convective instabilities due to biophysical reaction and diffusion in myocardium kinetic reaction, and (3) strong local coupling. All of these three instabilities are responsible for the mode coupling between calcium oscillation and the plane wave of Lamb waves in the viscoelastic cardiac plate of interventricular septum. |
