The cause of VT/VF is spiral wave reentry(SWR). In recent years, an endoscope was inserted into the left atrium of the sheep heart, and action potential of left atrium was measured simultaneously by optical mapping method using two high speed cameras, endocardium and epicardium at the same time research has been reported. As a result, it has been suggested that I-shaped type filament, which is the SWR center, stays in a site where the myocardial wall thickness changes drastically. However, in the ventricle, anatomical structure is complicated and measurement signals require high resolution, so simultaneous measurement of action potential signals is not done sufficiently. Therefore, in this research, we developed a system that can simultaneously measure action potential signals using two high speed cameras, and we report the phase analysis method which quantitatively shows the correlation between anatomical structure and I-shaped type filament which is the SWR center.
