'''Note:''' It is important to realize that not all these steps may be applicable when you encounter ECG abnormalities. If, for example, the rhythm is not sinus in the [[Rhythm|first step]], the algorithm to analyze [[
dysrhythmias]] should be followed. If a [[LBBB|Left Bundle Branch Block]] is present in [[Conduction|step 3]], [[ST morphology]] will be strongly influenced by this defect.
Finally the '''real world''' is presented through [[Cases and Examples|'''practice ECGs''']].
Afteryou have finished the course you are invited to come back to read more about abnormal ECGs in the '''ECG textbook'''.
