Positive ECG sign(s) of ischemia in Tread mill test is/ are- 
Select and explain. 
A. Upsloping depression of the ST segment mV below baseline, B. Downsloping depression of the ST segment >0.1 mV below baseline, C. Junctional ST-segment, D. Tachycardia
B: Downsloping depression of the ST segment >0.1 mV below baseline
Answer: B: Downsloping depression of the ST segment >0.1 mV below baseline 
Explanation: Answer- B. Downsloping depression of the ST segment >0.1 mV below baselineThc ischemia ST:-segment respone generally is defined as flat or downsloping depression of the ST segmant >O.1 mVbelow baseline (i.e., tha PR segnent) and lasting longer than O.08s.Upsloping or junctional ST-segment changes are not considered characteristic of ischemia and do not constitute a positive test.
