# 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
