Atrial septal aneurysm mimicking ECG signs of enlarged right atrium
Third Department of Internal Medicine (Cardiology), University Hospital Heidelberg, Im Neuenheimer Feld 410, 69120 Heidelberg, Germany
In a routine ECG from a young asymptomatic woman, changes in P-wave morphology and the frontal plane atrial vector were noted. Two-dimensional echocardiography revealed a large atrial septal aneurysm as probable underlying cause. This case report demonstrates that non-specific right atrial ECG signs may be indicative of lone atrial septal aneurysm.
