My first product manager job was that of assistant product manager for Marquette Electronics, the leader in cardiology electronics. My assigned product area was exercise tolerance testing (ETT) or “stress testing”. In the world of stress testing in 1994, there were a few electrocardiographic technologies that were making use of the first digital stress testing, the CASE12, which was also the largest selling stress testing system of all time.
In the world of stress testing device development, there was very little to be competitive about. Quinton was the market leader owing to designing the first treadmill/ekg machine combination.
