Why the study?
Does the change in QT dispersion after quinidine administration predict the acute antiarrhythmic response in patients with ventricular tachycardia?
Population
36 patients with inducible ventricular tachycardia during programmed electrical stimulation (PES)
Comparison
Quinidine vs Baseline (pre-quinidine measurements)
Design
Cohort
Follow-up
Acute (during repeat PES study)

QTc dispersion rise after quinidine may flag nonresponse in VT; leaves open predictive value pending prospective validation.
Does the change in QT dispersion after quinidine administration predict the acute antiarrhythmic response in patients with ventricular tachycardia?
An increase in QT dispersion following quinidine administration is associated with a lack of efficacy in preventing inducible ventricular tachycardia.
Kertland et al. (2000) studied this question.
