   FOR IMMEDIATE RELEASE

                    Marquette, Physio-Control Forge Alliance 

          Agreement will enhance treatment of emergency cardiac events


   Milwaukee, Wis. and Redmond, Wash.   February 25, 1997  --  Medical device
   industry leaders Marquette Medical Systems and Physio-Control Corporation
   today announced a strategic alliance to create technological compatibility
   between their cardiology products and to develop a joint distribution
   strategy.

        The alliance will allow emergency medical teams equipped with a
   Physio-Control portable heart monitor/defibrillator with 12-lead
   capability to capture an electrocardiogram (ECG) from a suspected heart
   attack victim and immediately transmit the waveforms to the Marquette MUSE
   CV/TM/ cardiovascular information system installed at the hospital  
   before the patient is even placed in an ambulance.  Emergency department
   physicians will be able to save valuable minutes by reviewing waveforms at
   the hospital and then ordering the start of treatment before the patient's
   arrival.  

        "This partnership will integrate cardiac response and transmission of
   cardiovascular information - and help save lives," Physio-Control Chairman
   and CEO Richard Martin said.

        The two companies will exchange proprietary technologies such as the
   Marquette 12SL/TM/ ECG Analysis program for use in Physio defibrillators,
   and the Physio biphasic defibrillation technology for use in Marquette
   modular patient monitors.  Also, Marquette and Physio will investigate
   joint development of other products using shared knowledge and techniques.

        Marquette and Physio will work together to expand distribution of
   both companies' products in North America as a means to better meet
   customer needs, enhance product competitiveness and reduce operating
   expenses.  In addition to their own products, they will represent each
   other in appropriate market segments.  Marquette's exclusive defibrillator
   offering in the North America hospital market will be the Physio line of
   products.  Also, Physio will represent Marquette products in certain
   sectors of the North America hospital and out-of-hospital markets.

        As a result, customers of both companies will have easy access to a
   more complete line of products and services for response to cardiac
   emergencies.

        "This agreement demonstrates our joint commitment to improve chest
   pain management and increase survival rates for heart attack," said
   Marquette President Tim Mickelson.  "Our two companies will work closely
   together to provide a 'seamless connectivity' for the patient's data at
   each point of care.  We will do whatever it takes to make sure the
   patient's ECG is in the doctor's hands as quickly as possible."

        Physio-Control International Corporation (Nasdaq: PHYS) introduced
   portable defibrillation technology nearly 30 years ago.  Based near
   Seattle, Wash., the company manufactures, sells and services a broad range
   of defibrillator/monitor/pacemakers and other medical instruments.

        Milwaukee, Wis.-based Marquette Medical Systems, Inc. (Nasdaq: MARQA)
   manufactures medical electronics equipment, software and systems for
   diagnostic cardiology, patient monitoring and integration of clinical
   information.  Established in 1965, Marquette developed the first central
   ECG storage system.
