Validates isolated papillary muscle models for cardiac energetics at low frequencies; leaves open applicability at higher rates or in vivo translation.
Energy stores in isolated cat papillary muscles remain intact for at least 3 hours at 12 contractions/minute at 26°C, validating the preparation's energy integrity for physiologic studies.
Pool et al. (1968) studied this question.
