Key Points

To observe the long-term effects of atrial septal pacing on interatrial block and sinus rhythm.
Conducted a fifteen-year electrocardiographic follow-up on a single patient with interatrial block.
Utilized atrial septal pacing to optimize interatrial conduction.
Atrial septal pacing helped maintain sinus rhythm in the patient.
There was a notable remodeling of the atrium over the follow-up period.

Implication

Long-term follow-up reveals how atrial septal pacing maintains sinus rhythm in a patient with interatrial block.

Abstract

Long-term electrocardiographic follow-up captured the progression of IAB in a single patient. High atrial septal pacing optimized interatrial conduction and helped maintain sinus rhythm in a markedly remodeled atrium.
