Peculiarities of reactions of ionotropic and chronotropic heart function in mature rats after adreno stimulants administration

For the first time, studies have been carried out to study the response of SV to the introduction of β, α1 and α2-agonists. It was found that in the process of muscle training, the most pronounced increase in the response of heart rate occurs to the introduction of an α2-adrenergic stimulator. It has been established that in the group of animals subjected to the regime of limited motor activity, i.e. hypokinesia, there is an increase in the response of heart rate to the introduction of β-, α1- and α2-adrenergic stimulants. Therefore, it can be argued that in animals subjected to a regimen of limited motor activity, sympathetic activity remains at a high level.
