Main outcome measurements: Competition time, beat-to-beat blood pressure by the vascular unloading technique, oscillometric blood pressure, beat-to-beat stroke volume by impedance cardiography, total ...

A minimal change in heart rate (<15 bpm) following a change from a supine to a standing posture in the presence of hypotension indicates baroreceptor reflex impairment, whereas tachycardia (>15 ...

The regulation of blood pressure by the baroreceptor reflex was examined in anesthetized dogs. The receptor feedback path was broken by surgical intervention, the input (carotid sinus pressure) was ...

This paper describes the integration of computational models of the cardiovascular system, the cardiac electrical activity and the baroreceptor reflex of the autonomic nervous system, with a model ...

Baroreceptor sensory nerves terminate in the adventitia of the carotid sinuses and aortic arch and play a major role in the reflex regulation of the circulation. 12 Baroreceptor activity is influenced ...

The exact mechanism of this increased sensitivity is largely unknown but is hypothesized to be related to diminished baroreceptor reflex activity, resistance of cardiac adrenergic receptors to ...

Lectures on conditioned reflexes by Pavlov, Ivan Petrovich, 1849-1936 Publication date 1928 Topics Brain -- Localization of functions, Brain, Conditioned response Publisher London : M. Lawrence ...

Baroreceptors, sensors that play a role in controlling arterial blood pressure (BP), are mechanical stretch receptors located in the aortic arch and carotid sinuses. Factors affecting the degree of ...

Introduction Autonomic function is essential for blood pressure control and baroreceptor sensitivity (BRS) acts as a composite marker of overall function. Both sympathetic and parasympathetic function ...
