In the treatment of these wells,micro-seismic and tilter meter were used to monitor the fracture spreading.After refracturing,the production histories of oil wells were matched with nume...

Isochrones were displayed both during sinus rhythm and AF.Results During sinus rhythm,the atrial excitation wave front begins from sinus node spreading to right atrium(RA)and left atrium(LA).
