The influence of xyla and meditine on functional activity of cardiovascular system of cats under surgical manipulations

The data on the influence of sedative alpha-2- agonists - xyla and meditine on functional condition of cardiovascular system of the cat are presented in the study: heart rate, speed of passing of an im-pulse on carrying-out heart system, the existence of violations of heart rhythm. The research was con- ducted on clinically healthy cats coming to educa- tional and scientific methodical veterinary center of "Vita" of Krasnoyarsk SAU. Two groups of animals up to 30 heads in each were created. The cats of the first group were injected with xyla in a dose of0.15 ml on 1 kg of weight one time intramuscularly, the cats of the second group - meditine 0.5 ml on 5 kg of weight intramuscularly once. In all cats, se- dated with xyla, steady decrease in heart rate to 90-112 beats/min (at a rate of 140 beats/min) was established, the lengthening of the R-R interval by 1.5-2 times (from 0.65 up to 0.9 seconds), as well as a significant increase in the time of repolariza- tion of the heart muscle (t wave and t-R interval -0...
