Three-dimensional mapping discovered arrhythmic substrate missed in the initial diagnosis of idiopathic ventricular fibrillation

Abstract

During an initial diagnosis of IVF, an arrhythmic substrate may be missed for several reasons such as lack of information; thus, a careful follow-up is important. A three-dimensional mapping may identify a possible missed arrhythmic substrate in IVF.
