Rate-of-rise may predict quinidine QTc risk better than levels; leaves open whether kinetics should guide monitoring.
What is the relationship between serum quinidine levels, rate of rise of quinidine concentration, and QTc prolongation?
The rate of rise of quinidine concentration is a stronger predictor of QTc prolongation than absolute serum levels, highlighting the importance of absorption kinetics in its cardiac effects.
Edwards et al. (1974) studied this question.
