Abstract:
Since inappropriate sinus tachycardia (IST) occurs due to various reasons, it can be diagnosed after exclusion of all causes and diseases that may result in sinus tachycardia. In particular, it is important to differentiate postural orthostatic tachycardia syndrome (POTS), and a multidisciplinary approach is necessary for differentiating psychiatric events. In addition, whether the clinical symptoms coincide with tachycardia events should be checked before treatment. β-adrenergic blocker is the most effective drug, and exercise training is recommended for controlling clinical symptoms. Furthermore, discontinuation of smoking and alcohol consumption, and decrease in caffeine intake may be useful. Recently, ivabradine has been found effective, and catheter ablation can be considered in cases of drug refractory IST presenting with clinical symptoms.
