Sinoatrial nodal reentrant tachycardia: a case report and literature review

This case highlights the diagnostic challenges associated with SANRT and emphasizes the role of CSM as both a diagnostic and therapeutic intervention. Early recognition of SANRT is crucial, as it can mimic other supraventricular arrhythmias, leading to mismanagement. While electrophysiological studies remain the gold standard for diagnosis, non-invasive measures such as vagal maneuvers can be highly effective in terminating the arrhythmia and providing symptomatic relief.
