This physiological study demonstrates the recording of transmembrane cardiac potentials in human ventricles during surgery under different temperature conditions.
Transmembrane cardiac potentials from the human ventricles were recorded in 10 subjects during corrective cardiac surgery under normothermic or hypothermic anesthesia. The amplitude and shape of these transmembrane potentials are compared with simultaneously recorded electrocardiograms, and their relationships are discussed.
Bromberger‐Barnea et al. (Thu,) studied this question.
