VF or Ventricular Fibrillation is a life-frightening heart rhythm called cardiac arrhythmia. It is illustrated by chaotic electrical movement in the ventricles, resulting in the lack of adequate compaction and a compromised output of cardiac. VF mapping has developed as an important method to understand the inherent processes and optimize treatment procedures. This article gives an outline of the technologies, trends, and outlooks in mapping VF in order to assess cardiac output. The introduction portion highlights the importance of mapping VF in enhancing the outcomes of patients and directing restorative intervention. It highlights the restrictions of methods that are traditional and the demand for more comprehensive and precise methods of mapping.
