This early experimental study demonstrated that the relationship between heart rate and transmembrane potential duration in isolated human hearts mirrors the QT-time-frequency relationship seen in clinical ECGs.
Answers are grounded in this paper and cite their sources.
These isolated-heart data leave open whether plateau-phase dynamics explain clinical QT-rate adaptation; in vivo validation required.
