This　article　presents　an　accurate　detection　design　of　onmi-directional　M-mode　cardiography　system,　gives　detailed　analysis　about　synchronous　tracking　between　data　direction　line　and　heart　deformation,　also　provides　the　concrete　implementation　steps.　Quantitative　analysis　data　of　systolic　and　diastolic　heart　campaign　and　its　deformation　can　be　more　accurately　detected　through　the　design.　We　designed　a　four-dimensional　tracking　model　for　heart　deformation　and　an　improved　genetic　algorithm　for　analyzing　the　model.　The　system　realizes　the　optimal　design　of　the　state　invention　patent　＇the　onmi-directional　M-mode　cardiography　and　its　system　98　125713.5＇.
