Sinoatrial Reentry Tachycardia: A Review

Abstract

Sinoatrial reentry tachycardia is a relatively uncommon arrhythmia in the literature, but may be prone to underdiagnosis due to electrocardiographic similarity to sinus tachycardia and misinterpretation of symptoms as psychosomatic. Awareness of the diagnosis, and hence differentiation of SART from inappropriate sinus tachycardia, atrial tachycardia or non-cardiac diagnoses paves the way for adequate therapy. While medication (digoxin, verapamil and amiodarone) may be successful or even desirable under certain conditions, radiofrequency catheter ablation offers curative therapy in most cases with few adverse effects.
