Prolonged P-wave duration may reflect delayed atrial conduction in unrepaired secundum ASD; hypothesis-generating for arrhythmia risk and should not yet change practice.
Does unrepaired secundum atrial septal defect result in prolonged P-wave duration compared to healthy controls?
Adults with unrepaired secundum ASD exhibit prolonged P-wave duration indicative of delayed atrial conduction, independent of atrial enlargement.
