[Functional and morphologic changes in the heart following phrenicotomy]. / Funktsional'nye i morfologicheskie izmeneniia v serdtse posle frenikotomii.

Experiments on dogs showed that the phrenic nerves participate in innervation of the heart. Their division in the cervical portion is attended with disorders of the rhythm, abnormalities in the components of the electrocardiogram, and degenerative changes in the intramural nerve apparatus of the heart. The results of the experiments indicate that the use of the phrenic nerve as a donor in a plastic operation of the nerve trunks should be considered an operation of choice.
