Quizplus · Accepted Answer

Sinoatrial node re-entry tachycardia (SANRT) is a rare tachydysrhythmia that results from a re-entry circuit around the SA node. It is characterized by fast regular atrial rates and narrow QRS complexes on ECG. Regular narrow complex tachycardia (A) and paroxysmal atrial tachycardia (C) can refer to various types of supraventricular tachycardia, including SANRT. AV node re-entry tachycardia (D) involves a re-entry circuit within the AV node, not the SA node.
