The three most common forms of ASD are: secundum, sinus venosus, and primum defects. Secundum ASD The most common form of an atrial septal defect is presence of ostium secundum type in the middle of the septal defect, while less common is ostium primum type, located lower in the septum and in these cases there are abnormalities in the mitral tricuspid valves. In primum defects left axis deviation is seen in most patients with an axis of > -30 degrees and very few patients have right axis deviation. In contrast ostium secundum defects have an axis between 0 degrees and 180 degrees with most cases to the right of 100 degrees.

In addition to the PR prolongation, individuals with a primum ASD have a left axis deviation of the QRS complex, while those with a secundum ASD have a right axis deviation of the QRS complex. Individuals with a sinus venosus ASD exhibit a left axis deviation of the P wave (not the QRS complex). The frontal plane QRS is the most helpful clue to distinguish between an ostium secundum ASD and an ostium primum ASD. In primum defects left axis deviation is seen in most patients with an axis of > -30 degrees and very few patients have right axis deviation.
