J-Point Elevation in Survivors of Primary Ventricular Fibrillation and Matched Control Subjects

Clinical Questions

  • In patients without structural heart disease, is the presence of J-point elevation a marker for arrhythmic risk?
  • Does the presence of J-point elevation, either with or without ST-segment elevation, in leads other than V1┬áto V3, exist as an innocent finding, or is this a marker associated with a history of VF in patients without structural heart disease?
  • Is J-point elevation more prevalent in younger individuals?

Bottom Line

Although J-point elevation is found more frequently among patients with idiopathic VF than among healthy controls, its presence should not be interpreted as a marker for increased risk when incidentally detected via screening.
