The new guidelines for the management of supraventricular tachycardia (SVT) were published by the European Society of Cardiology (ESC) in September 2019. The key message of the guidelines is that catheter ablation should be offered as a first line treatment to most patients during a comprehensive discussion of the risks and advantages. This recommendation recognizes that catheter ablation has nowadays become a widely established, effective and safe treatment method with a very low complication rate, which has revolutionized the treatment of SVT due to the substantial technical developments in recent years...

Supraventricular tachycardias (SVT) are common, with atrioventricular nodal reentry tachycardias (AVNRT) being the most common paroxysmal supraventricular tachycardia. The pathophysiological understanding and the catheter ablation of SVTs have developed steadily in recent years. For example, dividing AVNRT into "typical" and "atypical" depending on the HA-, VA-interval and AH/HA ratio is recommended. Because of higher rates of recurrences after cryoablation, radiofrequency ablation has prevailed in AVNRT...

Sustained fetal supraventricular tachycardia (SVT) complicated by hydrops fetalis carries a significant risk of morbidity and mortality. While there is no clear consensus on first- and second-line therapy options for the management of fetal SVT with or without hydrops fetalis, there exists significant nonrandomized experience with a number of antiarrhythmic agents that has founded the basis for management. Furthermore, recently published meta-analyses and ongoing multicenter prospective studies have aimed to bridge the gap in the literature...

Splanchnic vein thrombosis (SVT) including portal, mesenteric, splenic vein thrombosis and the Budd-Chiari syndrome, is a manifestation of unusual site venous thromboembolism. SVT presents with a lower incidence than deep vein thrombosis of the lower limbs and pulmonary embolism, with portal vein thrombosis and Budd-Chiari syndrome being respectively the most and the least common presentations of SVT. SVT is classified as provoked if secondary to a local or systemic risk factor, or unprovoked if the causative trigger cannot be identified...

OBJECTIVE: Performance and symptom validity tests (PVTs and SVTs) measure the credibility of the assessment results. Cognitive impairment and apathy potentially interfere with validity test performance and may thus lead to an incorrect (i.e., false-positive) classification of the patient's scores as non-credible. The study aimed at examining the false-positive rate of three validity tests in patients with cognitive impairment and apathy. METHODS: A cross-sectional, comparative study was performed in 56 patients with dementia, 41 patients with mild cognitive impairment, and 41 patients with Parkinson's disease...

BACKGROUND: The electrocardiogram (ECG) is essential for the differential diagnosis of wide QRS complex tachycardia (WCT). OBJECTIVE: To evaluate the diagnostic value of a novel ECG algorithm based on the morphologic characteristics of the QRS on the limb leads. METHODS: Limb Leads Algorithm (LLA) was evaluated by analyzing 528 monomorphic WCTs with electrophysiology (EP)-confirmed diagnoses. In the LLA, ventricular tachycardia (VT) is diagnosed in the presence of at least one of the following: ⑴ monophasic R wave in lead aVR; ⑵ predominantly negative QRS in leads I, II, III; ⑶ Opposing QRS complex in the Limb leads (OQL): concordant monophasic QRS complex in all three inferior leads; AND concordant monophasic QRS complex in two or three of the remaining limb leads with an opposite polarity to that of the inferior leads...

Supraventricular tachycardia (SVT) is one of the most common conditions requiring emergency cardiac care in neonates. Atrioventricular reentrant tachycardia utilizing an atrioventricular bypass tract is the most common form of SVT presenting in the neonatal period. There is high likelihood for spontaneous resolution for most of the common arrhythmia substrates in infancy. Pharmacological agents remain as the primary therapy for neonates.

BACKGROUND: Nodofascicular and nodoventricular (NFV) accessory pathways connect the atrioventricular node and the Purkinje system or ventricular myocardium, respectively. Concealed NFV pathways participate as the retrograde limb of supraventricular tachycardia (SVT). Manifest NFV pathways can comprise the anterograde limb of wide-complex SVT but are quite rare. The purpose of this report is to highlight the electrophysiological properties and sites of ablation for manifest NFV pathways...
