Left atrial isomerism can present as asymptomatic sinus bradycardia requiring pacemaker implantation, highlighting the importance of considering congenital heart disease in arrhythmic disorders.
INTRODUCTION: The eterotaxic syndromes encompass two main anatomic pictures: left and right atrial isomerism. They cause a distortion of the atria anatomy that may involve the conduction tissue. The prognosis is related to the severity of the intracardiac-associated defects. CASE REPORT: We describe the case of a patient suffering from asymptomatic 'sinus' bradycardia since childhood, who was referred for pacemaker implantation, in which the diagnosis of left atrial isomerism was made. CONCLUSION: The present paper may provide new insights on the clinical course of arrhythmic disorders, in particular among patients with congenital heart disease.

Ferrero et al. (2008) conducted a case report in Left atrial isomerism and sinus bradycardia (n=1). Left atrial isomerism was evaluated on Diagnosis of left atrial isomerism. A patient with asymptomatic sinus bradycardia since childhood was diagnosed with left atrial isomerism upon referral for pacemaker implantation.
