Where is this myocardial infarction located?
Answer
Culprit lesion: RCA
- sinus bradycardia
- about 55/min
- normal conduction
- intermediate (normal) axis
- normal p wave morphology
- tall R in V2, otherwise normal QRS morphology
- ST elevation in II, III, AVF (in III > II). Depression in I, AVL, V2.
- Conclusion: Inferoposterior MI caused by a RCA occlusion
Arguments in favor of RCA occlusion (instead of RCX):
- ST depression in I, AVL
- bradycardia
- ST elevation in III > II ('the highest ST elevation points at the culprit lesion')
