This study examines how postnatal development affects the cardiac response to milrinone in guinea pig hearts, finding age-dependent variations in chronotropic, inotropic, and lusitropic effects.

This study characterizes age- and chamber-specific gene expression patterns in guinea pig and human hearts, identifying conserved maturation markers to support guinea pigs as a preclinical model for pediatric cardiology.

This study examines electroanatomical changes in guinea pig hearts from neonatal to adult stages, finding age-related differences in conduction velocity, action potential duration, and excitation-contraction coupling.
