Bruce Protocol

from Wikipedia, the free encyclopedia

The Bruce protocol is a special procedure for the ergometric measurement of cardiovascular exercise capacity. It is the most common standard protocol for examinations on a treadmill ergometer . After a rest phase of 3 minutes, the Bruce protocol contains a total of eight levels of increased stress, which are run through every 3 minutes. The load is achieved through a combination of different running speeds and inclination angles of the treadmill. During this examination, the power (given in watts ) is continuously monitored and an electrocardiogram (EKG) is recorded.

The protocol was developed in 1973 by the American cardiologist Robert A. Bruce (1916-2004) at the University of Washington .
