Medical device manufacturers PHYSIO-CONTROL CORPORATION and MARQUETTE MEDICAL SYSTEMS have formed a strategic alliance to create technological compatibility between their products and a joint distribution strategy. The alliance will allow emergency medical teams using Physio-Control`s 12-lead heart monitor/ defibrillators to transmit ECGs to Marquette`s MUSE CVTM cardiovascular information system at a hospital before the patient is placed in an ambulance. Hospital emergency physicians will be able to review the information and order immediate treatment before the patient arrives.
