Electrocardiogram Finding in Ventricular Fibrillation
J-point elevation appears more often in patients with ventricular fibrillation
TUESDAY, Sept. 30 (HealthDay News) -- J-point elevation is more common in the electrocardiograms of patients with idiopathic ventricular fibrillation than healthy individuals and athletes, according to the results of a study in the Oct. 7 issue of the Journal of the American College of Cardiology.
Raphael Rosso, M.D., from Tel Aviv University in Israel, and colleagues performed electrocardiograms on 45 patients with idiopathic ventricular fibrillation, 124 age- and gender-matched controls, and 121 young athletes.
The researchers found that J-point elevation was significantly more frequent among patients with ventricular fibrillation than controls (42 percent versus 13 percent). J-point elevation was more common in the inferior leads and in leads I to aVL, but not leads V4 to V6. J-point elevation was more common among males, and the frequency of J-point elevation in athletes was intermediate to that of patients with ventricular fibrillation and matched controls. ST-segment elevation and QRS slurring provided no additional diagnostic value, the authors note.
"J-point elevation is found more frequently among patients with idiopathic ventricular fibrillation than among healthy control subjects," Rosso and colleagues conclude.
