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.

Journal Club Recap

Thanks to everyone who came to journal club last night and thanks to Dr. Hollander for being a most generous host and for sharing his chest pain knowledge. The bottom line from the three articles discussed last evening was that there are specific clinical history points, alternative diagnoses, and cardiac risk factors which can help […]
