Key result
A simplified ventricular programmed electrical stimulation protocol induced appropriate arrhythmias in 88% of patients with ventricular fibrillation and 84% with sustained VT, with 95% specificity.
Why the study?
Does a specific ventricular programmed electrical stimulation protocol efficiently and specifically induce appropriate arrhythmias in patients with a history of ventricular arrhythmias?
Observational (n=481)
Does a specific ventricular programmed electrical stimulation protocol efficiently and specifically induce appropriate arrhythmias in patients with a history of ventricular arrhythmias?
A simplified ventricular programmed electrical stimulation protocol using up to 3 extrastimuli achieves high sensitivity and 95% specificity for inducing ventricular arrhythmias.
No takes yet. Share an insight, caveat, or question.
May support simplified PES for arrhythmia induction in select patients; hypothesis-generating, should not yet change practice.
Fisher et al. (1992) conducted an observational in Ventricular arrhythmias (n=481). Ventricular programmed electrical stimulation (PES) protocol vs. Control patients was evaluated on Inducibility of appropriate arrhythmias. A simplified ventricular programmed electrical stimulation protocol induced appropriate arrhythmias in 88% of patients with ventricular fibrillation and 84% with sustained VT, with 95% specificity.
