Early basic electrophysiology recordings demonstrate that human ventricular intracellular action potentials are morphologically similar to those of lower animals.
Answers are grounded in this paper and cite their sources.
May support animal models for human electrophysiology research; leaves open relevance to clinical arrhythmias.
Intracellular action potentials from human ventricular muscle have been recorded with the flexibly mounted ultramicroelectrode. The complete record, correlated with the lead I electrocardiogram, is presented. The size, duration and shape of the human potentials closely resemble those previously recorded from lower animals.
