Case Summary:
A 58-year-old man underwent surgical resection of a left atrial myxoma with concomitant mitral valve repair. Postoperatively, progressive atrioventricular conduction disturbances were observed, evolving from Wenckebach periodicity to a multilevel atrioventricular block.
Take-Home Message:
This case underscores the importance of a detailed electrocardiographic analysis to identify multilevel atrioventricular block and to avoid misclassification as complete atrioventricular block, with implications for prognosis and management.
