Electrocardiographic Examinations in Dogs With Experimental Hepatitis Contagiosa Canis

(Elektrokardiographische) EKG-Untersuchungen an Hunden mit experimenteller Hepatitis contagiosa canis.

EKG-undersökningar på hundar med experimentell Hepatitis contagiosa canis.

Summary

Dogs with experimentally produced Hepatitis contagiosa canis were subjected to repeated electrocardiographic examinations during the course of the disease. Varying degrees of depression of the STJ and S-T segments and deviations of the T-wave were noted. Serum-electrolyte studies made during the illness showed a decrease of potassium, sodium, and chlorides which did not seem to be the cause of the observed electrocardiographic abnormalities. Circulatory disturbances and changes in the endothelial cells described elsewhere are considered to be the cause of a disturbance in the metabolism and the function of the myocardium with resulting depression of the STJ and S-T segments and deviations of the T-wave.

Zusammenfassung

Hunde mit experimentell hervorgerufener H.c.c, wurden während des Krankheitsverlaufes wiederholt elektrokardiographisch untersucht. Man hat verschieden starke Senkungen vom STJ und S-T-Segment als auch Veränderungen der T-Welle beobachtet. Die gleichzeitig vorgenommenen Untersuchungen der Serumelektrolyte zeigen K-, Na- und Cl- Senkungen, die jedoch nicht als Ursache der beobachteten EKG-Veränderungen aufgefasst werden. Die in anderen Arbeiten beschiebenen Kreislaufstörungen und die Schädigungen des Endothels, werden als Ursache des veränderten Stoffwechsels und von Funktionsstörungen im Myokard mit Senkung des STJ und S-T- Segments und T-Wellen-deviation aufgefasst.

Sammanfattning

På hundar med experimentellt framkallad H.c.c. har under sjukdomsutvecklingen upprepade EKG-undersökningar företagits. Varierande grad av sänkninger av STJ och S-T segment och förändringar av T-vågen har konstaterats. Parallellt företagna serumelektrolytundersökningar visar K-, Na- och Cl- sänkningar, vilka dock icke synes vara orsak till de konstaterade EKG-förändringarna. I andra arbeten beskrivna cirkulationsrubbningar och endotelcellskador, anses vara orsak till ändrad metabolism och funktionsstörning i myokardiet med sänkning av STJ och S-T segment och T-vågsdeviationer som följd.
