We present a case of a pre-adolescent girl with mitral stenosis caused by rheumatic fever. The 12‑lead ECG showed prolonged P-wave duration indicating interatrial block. In addition, the P waves in the inferior leads showed a transient atypical interatrial block with a triphasic pattern in lead II. The appearance of the atypical interatrial block resulted in the attenuation of the P terminal force in lead V1. Atypical interatrial block is associated with atrial cardiomyopathy and is a potential risk factor for atrial fibrillation or stroke.
