The anatomic and ECG features of 23 patients with polysplenia and 17 patients with asplenia were reviewed. Patients with polysplenia tended to have a superiorly oriented P wave axis. In asplenia the P wave axis was inferiorly directed, but not in the normal location. We were unable to correlate the abnormal P wave axis with specific anatomic features of the atria.
