Abstract: An aspect of the present disclosure calculates a phase variance value indicating a degree of variance of a phase in a surrounding of each position in a biological tissue, based on phase values of excitation wave at respective positions in the biological tissue that acts in response to excitation caused by propagation of the excitation wave in the tissue, and generates an analysis map, based on a time series of at least part of the phase variance values at the respective positions. Since the phase variance value indicates the degree of variance of the phase in the surrounding, a position having a large degree of variance of the phase in the surrounding may be specified as a rotation center of rotating excitation wave.

Abstract: A home or personal care product comprising a gel, characterised in that the gel is formed from dimethyl acrylamide monomer crosslinked with a crosslinker and polymerised under conditions that cause the polymer to form a pattern due to corrugation or deformation in gel thickness of the order of 0.3 mm, preferably 0.5 mm or greater (macroscopic deformation visible to the naked eye).

Abstract: [PROBLEMS] To prevent ventricular fibrillation. [MEANS FOR SOLVING PROBLEMS] A rectangular base material (10) is sewn to the epicardium surface of a left ventricle (38). Four cooling Peltier elements (12) are provided at the center of the base material (10), and temperature-detecting thermistors (18) are provided at part of their peripheries. A plurality of circular, flat potential sensors/energizing electrodes (14) for detecting the surface potential of the heart are arranged in a lattice form on the surface of the base material (10) at almost equal intervals. The potential sensors/energizing electrodes (14) are energizing electrodes for delivering a pulse voltage/current to the heart. When a rapid ventricular rate is detected, these Peltier elements (12) are energized to cool the heart.
