Supraventricular tachycardia - ECG interpretation and clinical management].

Supraventricular tachycardia (SVT) is a very common cause of hospital admission and its diagnostic and treatment may be difficult sometimes. While vagal maneuvers or intravenous adenosis administration during 12-lead ECG recording should be performed in hemodynamically stable patients for diagnosis and treatment, hemodynamically unstable patients should be carioverted immediately. The new ESC guideline (2019) on diagnosis and clinical management of SVT significantly upgrades catheter ablation and gives it a new preferential status. For example, in patients with symptomatic recurrence, atrioventricular nodal re-entrant tachycardia should be ablated due to the very low risk of AV block. Furthermore, catheter ablation should also be offered as first-line therapy to patients with reentrant and focal arrhythmias. The diagnosis and therapy of tachycardiomyopathy is of particular importance and treatment should incorporate the ablation of the underlying supraventricular tachycardia. The therapy of supraventricular tachycardia during pregnancy should be free of antiarrhythmic medication, especially in the first trimester. If ablation is necessary during pregnancy, only fluoroscopy-free mapping systems should be used. This review covers aspects of ECG diagnosis and guideline-based treatment of SVT. Thieme.
