  • The heart remembers : observations of cardiac memory in the Dorper sheep heart 
    Webb, E.C. (Edward Cottington); Ker, James A.; Bekker, P.A .; Boomker, Jacob Diederik Frederik (Pretoria : Agricultural Research Council, ARC-Onderstepoort Veterinary Institute and the University of Pretoria, Faculty of Veterinary Science, 2003)
    Memory is a property common to a diverse range of tissues. Cardiac memory has been demonstrated in the human, dog, rat and rabbit. This is a peculiar phenomenon reflected in the T wave of the electrocardiogram. The heart ...

    Horak, Ivan Gerard; Boomker, Jacob Diederik Frederik (Published jointly by the Agricultural Research Council, ARC-Onderstepoort Veterinary Institute and the Faculty of Veterinary Science, University of Pretoria., 2003)
    At monthly intervals for periods ranging from 9 to 25 consecutive months between three and four Merino yearling-sheep and two Merino lambs on three farms in Eastern Cape Thornveld, and two Dorper yearling-sheep on a farm ...
  • Ventriculo-atrial conduction in the ovine heart, caused by premature ventricular complexes 
    Ker, James A.; Webb, E.C. (Edward Cottington); Boomker, Jacob Diederik Frederik (Published jointly by the Agricultural Research Council, ARC-Onderstepoort Veterinary Institute and the Faculty of Veterinary Science, University of Pretoria., 2003)
    In humans, and certain animals, the atrioventricular conduction system is capable of bidirectional conduction. Depolarization impulses, originating in the ventricle itself, may thus be conducted in a retrograde direction ...
