V3 is positioned at V4R.

The ECG

Following the 7+2 steps:
- Rhythm
  - The ECG shows a regular rhythm. Every P wave is followed by a QRS complex. P waves are positive in I and AVF. Normal sinus rhythm
- Heart rate
  - 40 bpm
- Conduction (PQ,QRS,QT)
  - PQ: 160ms QRS: 90ms QT: 420ms QTc: 360ms
- Heartaxis
  - QRS positive in I and AVF: normal heart axis
- P wave morphology
  - Normal P wave morphology
- QRS morphology
  - Pathologic Q waves in III and AVF. QS in V1 and V2. No ST elevation in V3 (=V4R).
- ST morphology
  - ST elevation in II, III, AVF and V5. ST depression in I, AVL.
- Compare with the old ECG (not available, so skip this step)
- Conclusion?

sinusbradycardia with inferior-lateral myocardial infarction.
