Malnutrition is responsible for a number of alterations that occur in the organism, including alterations in the cardiovascular system. We hypothesize that long periods of malnutrition occurring after weaning may also be responsible for alterations in the cardiovascular system. Wistar rats were separated into the two following experimental groups: a labina® diet-fed control group (CG) and a malnourished group (MG), fed a multi-deficient diet. Results showed that the mg presented significantly lower body weight (p &lt; 0.001) in rats of all ages, higher heart rate (HR) (p &lt; 0.05) when rats were 3, 4 and 5 months old and lower HR in rats from 6 to 9 months of age, in relation to the CG. Spectral analysis showed a significant increase in the low...

Standard electrocardiographic values in Holstein calves
Provedor de dados: 45
Autores: Mendes,L.C.N.; Camacho,A.A.; Alves,A.L.G.; Borges,A.S.; Souza,R.C.A.; Ferreira,W.L.
This paper presents electrocardiographic values in 25 Holstein calves using the standard bipolar limbs leads (I, II and III), augmented unipolar limb leads (avL, avR and avF) and a bipolar chest lead (V10). Two groups with different ages were compared (newborn - 18 to 72 hours and calves - 27 to 33 days old). It was concluded that no differences between age groups in P, Q, R, S and T waves, in the PR, QRS, QT and ST intervals and in axis orientation were observed.
