“…20 The radiographs and ECG were consistent with the final diagnosis wherein pulmonary overcirculation and an AV nodal conduction disturbance, likely due to myocardial stretching secondary to right-sided volume overload, were identified, respectively. 21 The ECG also revealed a marked left QRS shift as a result of a left ventricular conduction anomaly.…”

“…It is well known that complete and incomplete RBBB is the most frequent ECG marker of ASD. 5–10 ASD may also be associated with other impulse conduction disorders, particularly with prolonged P-R interval. 6 RBBB might be due to right ventricular volume overload or as a result of true delay of impulse conduction on the right bundle branch 5,6 whereas prolonged P-R interval may be explained by the atrial enlargement and increased distance for internodal conduction.…”

Interatrial septal disorders, which include: atrial septal defect, patent foramen ovale and atrial septal aneurysm, are frequent congenital anomalies found in adult patients. Early detection of these anomalies is important to prevent their hemodynamic and/or thromboembolic consequences. The aims of this study were: to assess the association between impulse conduction disorders and anomalies of interatrial septum; to determine the prevalence of different types of interatrial septum abnormalities; to assess anatomic, hemodynamic, and clinical consequences of interatrial septal pathologies. Fifty-three adult patients with impulse conduction disorders and patients without ECG changes but with signs of interatrial septal abnormalities, who were referred to our center for echocardiography, were included in a prospective transesophageal echocardiography study. Interatrial septal anomalies were detected in around 85% of the examined patients. Patent foramen ovale was encountered in 32% of the patients, and in combination with atrial septal aneurysm in an additional 11.3% of cases. Atrial septal aneurysm and atrial septal defect were diagnosed with equal frequency in 20.7% of our study population. Impulse conduction disorders were significantly more suggestive of interatrial septal anomalies than clinical signs and symptoms observed in our patients (84.91% vs 30.19%, P=0.002). Right bundle branch block was the most frequent impulse conduction disorder, found in 41 (77.36%) cases. We conclude that interatrial septal anomalies are highly associated with impulse conduction disorders, particularly with right bundle branch block. Impulse conduction disorders are more indicative of interatrial septal abnormalities in earlier stages than can be understood from the patient’s clinical condition.
