Short but Thick R Wave in V1: Posterior Infarction
Report:
Sinus rhythm 60/min
PR interval 0.20â
Old inferoposterior infarction
Comment:
Primary R wave in V1 ⥠0.04â is as much sign of posterior infarction as R > S configuration. Dominant R in V2-3 â the early transition â of course supports the diagnosis, especially with T waves still upright â but this can be a normal variant.
Inferior Q waves are rather thin, but present in all three inferior leads and associated with broad primary R in V1. Most posterior infarcts also show inferior Q waves.
