Key result
R on T extrasystoles were the most important factor initiating out-of-hospital ventricular fibrillation in patients with acute ischemic heart disease, occurring in 69% of cases.
Why the study?
What ECG factors predispose to the initiation of ventricular fibrillation outside the hospital in patients with acute ischaemic heart disease?
Observational (n=48)
What ECG factors predispose to the initiation of ventricular fibrillation outside the hospital in patients with acute ischaemic heart disease?
R on T extrasystoles and an increase in heart rate are key predisposing factors for the initiation of out-of-hospital ventricular fibrillation in patients with acute ischemic heart disease.
No takes yet. Share an insight, caveat, or question.
May prompt ECG vigilance for R-on-T in acute ischemia; leaves open whether targeted suppression reduces out-of-hospital VF.
Adgey et al. (1982) conducted an observational in Acute ischaemic heart disease with ventricular fibrillation (n=48). R on T extrasystoles were the most important factor initiating out-of-hospital ventricular fibrillation in patients with acute ischemic heart disease, occurring in 69% of cases.
