Answer
Culprit lesion: LAD
- sinustachycardia
- about 100/min
- normal conduction
- intermediate heart axis
- tall p wave in II consistent with right atrial dilatation. (the sawtooth-basline between the 2nd and 3rd complex in AVR is probably a motion artefact). PTA depression in II
- Loss of R waves throughout the anterior wall (V1-V6). QS complexes in V3-V5.
- ST elevation in V1-V5 with terminal negative T waves
- Conclusion: Large anterior MI due to LAD occlusion.
Characteristics that suggest a large infarct in this case are:
- Loss of R waves throughout the anterior wall (V1-V6). QS complexes in V3-V5.
- Left and right sided decompensation, resulting in right atrial dilatation and ischemia
- Tachycardia
