Does varying the ratio of dispersion of repolarization to action potential repolarization duration affect T wave symmetry and amplitude in a computer model?
Computer modeling demonstrates that cardiac T waves increase in amplitude and become more symmetric as action potential repolarization duration shortens with increasing heart rate, aligning with clinical observations.
Bernardo et al. (2002) studied this question.
