Characteristics of the circadian profile of heart rate during genetically determined hypertension

Characteristics of the circadian profile of heart rate during genetically determined hypertension

Abstract

Распространенность и значимость артериальной гипертензии в общей структуре заболеваемости определяет широкий круг задач перед исследователями. Важным компонентом в изучении механизмов развития гипертонической болезни являются хронобиологические показатели. Нами было предпринято исследование, направленное на изучение динамики циркадианного профиля частоты сердечных сокращений на различных жизненных сроках у самцов крыс линии SHR, с применением методики телеметрического мониторирования. Полученные результаты демонстрируют изменение характеристик сердечного ритма на разных временных интервалах, что было интерпретировано нами как подавление хронотропной функции сердца.

Prevalence and importance of hypertension in the general incidence structure determines a wide range of research problems. Chronobiological indices are of great importance in the investigatory activity concerning mechanisms of essential hypertension. Our work was focused on the dynamics of HR circadian profile at different terms in male SHR rats with the use of telemetry monitoring. The obtained data showed considerable changes of cardiac rhythm in different time intervals which was understood as inhibition of the chronotropic function of the heart.
