Sinoatrial nodal reentrant tachycardia: a case report and literature review.

ABSTRACT:

Background

Sinoatrial nodal reentrant tachycardia (SANRT) is a rare form of focal atrial tachycardia, often linked with structural or congenital heart disease. Due to its electrocardiographic similarities with other supraventricular tachyarrhythmias, it is frequently misdiagnosed.
