Background: Membranous interventricular septal aneurysm has been reportedto accompany atrioventricular (AV) conduction defects. If it is accompanied by AV block, patients generallybecome symptomatic before the age of 40. Case Report: A 65-year-old male presented with presyncope andextreme fatigue for one week. Resting ECG showed a 2: 1 AV block. Transthoracic echocardiography revealedan interventricular septal aneurysm without any shunt. After making the diagnosis of type 2 second-degreeAV block, a DDDR pacemaker was implanted. Conclusions: We presented a 65-year-old male with new-onsetpresyncope. A diagnosis of septal aneurysm and associated AV block was made and a pacemaker was implanted.
