Cardiac output and total peripheral resistance in spontaneously hypertensive rats.
ESPITE extensive studies on spontaneously hypertensive rats, there have been no studies on the cardiac output except a preliminary work by Albrecht et al,4) which reported a decreasing tendency of cardiac output with age. These authors employed the Stewart-Hamilton principle for the measurement of cardiac output. An attempt was made in this study to measure cardiac output in SHR by applying an ...
متن کاملCardiac output in conscious and almost unrestrained spontaneously hypertensive rats.
Cardiac output and arterial pressure in the conscious state were measured in spontaneously hypertensive rats and normal control rats with chronically implanted electromagnetic flow probe and arterial indwelling cannula. Cardiac index at rest was greater in hypertensive rats than in controls. However, the mean arterial pressure in probe implanted hypertensive rats was significantly lower than th...

Physiol. 221(Z) : 480-487. 197 1 .-The sensitivity of the carotid sinus baroreceptor reflex to step change in sinus pressure was studied in anesthetized dogs, with emphasis on the relative contributions of cardiac output (CO) and total peripheral resistance (TPR) i...
متن کاملCardiac parasympathetic hyperresponsiveness in spontaneously hypertensive rats.
The bradycardic response to baroreceptor stimulation is impaired in human and experimental hypertension. Because this bradycardia mainly depends on the vagus, this may reflect a reduced cardiac parasympathetic responsiveness, which would parallel the reduced cardiac adrenergic responsiveness observed in hypertension. To test this hypothesis, 12-week-old spontaneously hypertensive rats (n = 12) ...
متن کاملCardiac hypertrophy in spontaneously hypertensive rats.
The energy metabolism of cardiac hypertrophy in spontaneously hypertensive rats (SHR) was studied chronologically by histochemical and in part chemical methods. The activities of various enzymes, such as glucose-6-phosphate dehydrogenase (G6PDH), lactate dehydrogenase (LDH), isocitrate dehydrogenase, succinate dehydrogenase, beta-hydroxybutylate dehydrogenase (beta-HBDH) and monoamine oxidase (...
