* 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.'''
