- 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
- 100 bpm
- Conduction (PQ,QRS,QT)
- PQ: 140ms QRS: 100ms QT: 320ms QTc: 410ms
- Heartaxis
- QRS positive in I and AVF: normal heart axis
- P wave morphology
- The P waves have normal morphology.
- QRS morphology
- Narrow QRS. No left ventricular hypertrophy. No pathologic Q waves.
- ST morphology
- ST elevation in V1-V4 and lead I. ST depression in II, III, AVF and V6. Lead V3 shows V4R which is not elevated
- Compare with the old ECG (not available, so skip this step)
- Conclusion?
- Rhythm
Sinusrhythm with anteroseptal infarction. Ischemic vector is pointing upwards (ST depression in AVF), a sign of proximal LAD occlusion.
