An impact tool control method and apparatus and an impact tool using the same. This method describes a process by which sets of dynamic cardiopulmonary dependent variables are measured during steady-state conditions, displayed, and translated into quantitative and qualitative measurements while the independent variables of CRT, device lead placement and atrial-ventricular and interventricular delay settings of bi-ventricular pacemaker systems, are altered by a physician. The reaction mixture is refluxed at an elevated temperature to eventually produce a solution of the amine-terminated polyarylene polyether in the polar solvent. In addition, at least one variable which influences the operating dynamics of the vehicle is detected in the measurement means during the steering operation.
