Clinical

ST deviation (Maximum value during study) by EKG

Definition

ST-segment deviation represents the maximum ST deviation during a procedure such as an exercise stress test. In some contexts the maximum ST deviation may be defined more specifically, such as in the Duke Treadmill Score, which states that the ST deviation measurement should exclude any leads other than aVR that have pathological Q waves, and that it can be calculated during or after exercise.
