Overview
The mechanism of the arrhythmia primarily involves the sinus node and peri-nodal tissue[1] and does not require the AV node for maintenance. These patients have no apparent heart disease or other causes of sinus tachycardia. IST is thought to be due to abnormal autonomic control or dysautonomia. An autoimmune mechanism has been suggested as several studies have detected autoantibodies that activate beta adrenoreceptors in a portion of patients.[2][3]
