Echo-Doppler findings indicating a positive diastolic stress echocardiogram

1.	Increase (from rest) in the E velocity with exercise (to ≥ 80 m/s)
2.	Increase in the E/A ratio with exercise (to ≥  1)
3.	Increase in E/e′ (to ≥  12)
4.	Increase in peak TR velocity (to ≥  3.5 m/s). This finding must accompany one of the 3 above, to distinguish from exercise induced isolated pulmonary hypertension.

A = late transmitral diastolic velocity; E = early transmitral diastolic velocity; TR = tricuspid regurgitation.
