Symptom Burden Guiding Invasive Electrophysiological Study in Paroxysmal Supraventricular Tachycardia

The "Symptom Burden As Guiding Principle For Invasive Electrophysiological Study In Paroxysmal Supraventricular Tachycardia (Believe-SVT)" study was a multi-centre, retrospective, observational registry carried out in tertiary European hospitals. Inclusion criteria were: symptoms that were considered suggestive of paroxysmal supraventricular tachycardia by a cardiologist and/or cardiac electrophysiologist; absence of any sort of electrocardiographic tracing during episodes (including wearables and other single lead devices), and having undergone an electrophysiological study aimed at the diagnosis of paroxysmal supraventricular tachycardia.
