Idiopathic fascicular ventricular tachycardia and verapamil: how to administer a continuous perfusion

Idiopathic fascicular ventricular tachycardia is a rare form of ventricular tachycardia that is treated with verapamil, according to recent European guidelines. However, the authors and the majority of manufacturers only mention bolus intravenous administration of verapamil in these guidelines and in the Summary of Product Characteristics (SmPC), which leaves clinicians uncertain when continuous perfusion is required. This brief comment addresses this issue and suggests a protocol for the preparation and administration of continuous intravenous verapamil perfusion for adult patients.
