Answers:
Bruce Protocol
Stage mph % grade Duration

[1] 1.7 10% 3 minutes
[2] 2.5 12% 3 minutes
[3] 3.4 14% 3 minutes
[4] 4.2 16% 3 minutes
[5] 5.0 18% 3 minutes
[6] 5.5 20% 3 minutes

There are also "modified" Bruce protocols for those who are deconditioned or have a physical disability (elderly).
Injection of the contrast dye (Sestimibi more often than thallium) is performed one minute prior to total exhaustion. Significant EKG changes especially if symptomatic would cause the test to be ended abruptly. Chest pain without EKG changes however would not necessarily interrupt the stress test.
