***'''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.'''
***'''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'''
***'''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)
