  • Following the 7+2 steps:
    • Rhythm
      • This is a regular rhythm and every QRS complex is preceded by a p wave. The p wave is positive in II,III, and AVF and thus originates from the sinus node. Conclusion: sinus rhythm.
    • Hartfrequency
      • Use the 'count the squares' method (a bit less than 3 large squares ~> 300-150-100), thus about 110 bpm.
    • Conduction (PQ,QRS,QT)
      • PQ-interval=0.16sec (4 small squares), QRS duration=0.10sec, QT interval=320ms
    • Hartaxis
      • Positive in I, II, III, and AVF. Thus a normal heart axis.
    • P wave morphology
      • The p wave is rather large in II, but does not fulfill the criteria for right atrial dilatation.
    • QRS morphology
      • No pathologic Q waves, RsR pattern in V3, but the QRS-duration < 0.12 seconds thus no bundle branch block is present. No left ventricular hypertrofy: S in V1 + R in V5 < 35mm.
    • ST morphology
      • ST depressiion in II,III, and AVF and also in V5-V6. ST-elevation in AVL and V1.
    • Compare with the old ECG (not available, so skip this step)
    • Conclusion?

Acuut Anteroseptal Myocardial Infarction
