Conditions

Supraventricular Tachycardia

Brief summary

BELIEVE-SVT is a European multi-centre, retrospective registry in tertiary hospitals performing electrophysiological study in patients with palpitations considered clinically suggestive of paroxysmal supraventricular tachycardia by a cardiologist and without electrocardiographic documentation of tachycardia or preexcitation. Clinical characteristics, results of electrophysiological study and ablation, complications, and clinical outcomes during follow-up will be analysed.

Detailed description

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.
