This physiological study demonstrates the recording of transmembrane cardiac potentials in human ventricles during surgery under different temperature conditions.
Answers are grounded in this paper and cite their sources.
Does not alter clinical practice; leaves open further investigation of human ventricular transmembrane potentials under temperature variation.
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.
