ST elevation in II, III and aVF
This part of the heart muscle lies on the diaphragm and is supplied of blood bij the right coronary artery (RCA) in 8% of patients. In the remaing 20% the inferior wall is supplied by the ramus circumflexus(RCX).
An occlusion of the RCA can be distinguished of a RCX occulsuion on the ECG: in a RCA occlusion, there is ST depression in I and AvL and the ST-elevation is higher in III than in II. If the elevation is higher in II, suspect a RCX occlusion.
