| * 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.'''
