CDISC VENTRICULAR FIBRILLATION Ventricular_Fibrillation VFib Ventricular fibrillation VF Disease or Syndrome Ventricular Fibrillation is characterized by rapid, usually more than 300 bpm (cycle length: 180 ms or less), grossly irregular ventricular rhythm with marked variability in QRS cycle length, morphology, and amplitude. NICHD IMDRF:E060110 A disorder characterized by an electrocardiographic finding of a rapid grossly irregular ventricular rhythm with marked variability in QRS cycle length, morphology, and amplitude. The rate is typically greater than 300 bpm. (CDISC) FDA An irregular heart rhythm, usually associated with a rapid rate, that is caused by abnormal electrical activity within the ventricles. Ventricular Fibrillation Ventricular Fibrillation Patient Code (Appendix B) C0042510 A disorder characterized by a dysrhythmia without discernible QRS complexes due to rapid repetitive excitation of myocardial fibers without coordinated contraction of the ventricles.
