Understanding, Predicting, Preventing, and Treating Ventricular Arrhythmias: Pushing Sudden Death Into Overtime

Published:February 17, 2022DOI:
      Ventricular arrhythmias (VAs) have touched many lives, too often in tragic circumstances in the form of the sudden death of a family member or friend. Our understanding of sudden death has evolved as we journeyed from understanding VAs, to understanding the factors leading to their onset, and finally the interventions that can change the course of the natural history. In the early phase of recognition, the scope of the problem was compelling, with 1 in 1000 individuals suffering sudden death annually and being only rarely successfully resuscitated. Improvements in the treatment of atherosclerotic heart disease, ventricular dysfunction, heart failure, and VAs have, however, increased survival rate, reduced sudden death incidence, and improved quality of life in affected patients.
