Proposed chronic pharmacological treatment algorithm for patients with SCIVF. SCIVF, short-coupled idiopathic ventricular fibrillation.

∗Radiofrequency ablation of the initiating malignant PVC may be considered depending on local resources and expertise and patient characteristics (e.g. the presence or absence of frequent isolated premature ventricular contractions similar to those initiating the ventricular arrhythmias to allow for activation mapping).§Recommended starting dose of cilostazol is 100 mg twice daily. Recommended dose of bepridil is 200–400 mg once daily.
