Supraventricular Tachycardia

Anatomical Consideration in Catheter Ablation of Idiopathic Ventricular Arrhythmias

Idiopathic ventricular arrhythmias (IVAs) usually originate from the specific anatomical structures. For the past decade, major IVA origins from both endocardial and epicardial sites have been increasingly recognised (see Table 1).1–3 Catheter ablation of IVAs is usually safe and highly successful, but can sometimes be challenging because of the anatomical obstacles. Therefore, understanding the relevant anatomy is important to achieve a safe and successful catheter ablation of IVAs.

Consensus Document on Supraventricular Arrhythmias: A Valuable Initiative from EHRA

Supraventricular tachycardias (SVT) are common, with an estimated prevalence of 2.25/1,000 persons and an incidence of 35/100,000 person-years.1 Atrioventricular nodal reentrant tachycardia (AVNRT), in particular, represents the most common regular arrhythmia in the human, and its proportion increases with age.2 However, the European Society of Cardiology has not published management guidelines for SVT since its original 2003 document,3 while our colleagues in the US did so in 2015.4 In this respect, the recent initiative of the European Heart Rhy

Cardiac Arrhythmias in the Pregnant Woman and the Foetus

Neither supraventricular nor ventricular tachyarrhythmias are uncommon during pregnancy.1,2 When they are diagnosed, patients, relatives and physicians are frequently worried about ectopic beats and sustained arrhythmias.3,4 One should question whether arrhythmias should be treated in the same way as they would be outside pregnancy because all commonly used antiarrhythmic drugs cross the placenta.5 The pharmacokinetics of drugs are altered in pregnancy and blood levels need to be checked to ensure maximum efficacy and avoid toxicity.
