[The clinical significance of repetitive ventricular response induced by programmed electrical stimulation].

To clarify clinical significance of repetitive ventricular response (RVR), 50 patients with different kinds of heart disease were given ventricular programmed electrical stimulation. The results showed that: (1) The incidence of RVR is independent of heart disease, and it is as high as 83.87% even in the patients without organic heart disease; (2) There is no correlation between RVR and spontaneous ventricular tachycardias; (3) There may be some predictive value to the induction of monomorphic sustained ventricular tachycardias when RVR greater than or equal to 3 QRS complexes.
