Our patient's score was 11 points, meeting all criteria except left axis deviation
Serial electrocardiograms (Figure 3) showed left axis deviation
and changes compatible with anterior wall acute myocardial infarction.
This much left axis deviation
of the P wave is unusual in atrioventricular septal defect limited to the lowermost portion of the atrial septum, so-called ostium primum atrial septal defect (1, 2), but often is found when the entire atrial septum is missing (3, 4).
