Question

elevated ST segment in ECG is seen in- a.MI b.BBB c.1st degree heart block d.none​

Answer 1

Answer:

MI

Explanation:

ST segment elevation occurs because when the ventricle is at rest and therefore repolarized, the depolarized ischemic region generates electrical currents that are traveling away from the recording electrode; therefore, the baseline voltage prior to the QRS complex is depressed (red line before R wave).
