	*Is the R wave propagation normal? Normally R waves become larger from V1-V5. At V5 it should be maximal. If the R wave in V2 is larger than in V3, this could be a sign of a (previous) [[Posterior MI\|posterior myocardial infarction]]. Other causes are noted in the chapter [[Clockwise and Counterclockwise rotation]].		*Is the R wave propagation normal? Normally R waves become larger from V1-V5. At V5 it should be maximal.

	If all these ~~questions can be answered with 'no'~~ you can go on to the next step: [[ST morphology]].		If all these items are normal you can go on to the next step: [[ST morphology]].
