This article discusses aspects of the registrar accelerations and angular velocities to determine the power that develops a person while driving. Knowledge of this power with the simultaneous recording of electrocardiogram and possibly electromyogram lower limb muscles allows a comprehensive evaluation of the cardiovascular system. The use of inertial modules in modern cardiomonitors will significantly expand the diagnostic capabilities hidden ischemia in the early stages of the disease.
Keywords: inertial unit, walking, sensors, angular rate sensor, accelerometer, developed capacity, orientation of a rigid body, the quaternions
