* Following the 7+2 steps:
**Rhythm
***'''The ECG shows a regular rhythm with normal P waves (positive in I, III and AVF, negative in AVR), followed by QRS complexes. Sinusrhythm'''
**Heart rate
***'''78 bpm'''
**Conduction (PQ,QRS,QT)
***'''PQ: 180ms QRS: 160ms QT: 370ms QTc: 420ms
**Heartaxis
***'''Negative in III, AVF and AVR, positive QRS complexes in I, II and AVL: horizontal heart axis'''
**P wave morphology
***'''The P waves have normal morphology.'''
**QRS morphology
***'''Wide QRS complexes with [[[LBBB|left bundle branch block]]] pattern.'''
**ST morphology
***'''ST elevation in V1-V3, AVR. ST depression in I, II, III, AVF, V4-6. The Sgarbossa criteria for ischemia in LBBB are not met (nog concordant ST deviation, no ST depression V1-V3, nog discordant ST elevation > 5 mm).'''
**Compare with the old ECG (not available, so skip this step)
**Conclusion?
'''Sinusrhythm with left bundle branch block, comparison with an old ECG is mandatory to evaluate whether the LBBB is new (a sign of [[myocardial infarction]]) or old.'''
