A noninvasive measure of baroreflex sensitivity without blood pressure measurement.
BACKGROUND Baroreflex sensitivity (BRS) and heart rate variability (HRV) are attenuated in cardiovascular disease and can give important prognostic information. Conventional measures of BRS require expensive or invasive equipment for the beat-to-beat measure of blood pressure (BP). We examined the possibility of developing a simple protocol that would provide a relatively standardized BP stimul...
متن کاملBaroreflex Sensitivity Impairment During Hypoglycemia: Implications for Cardiovascular Control
Studies have shown associations between exposure to hypoglycemia and increased mortality, raising the possibility that hypoglycemia has adverse cardiovascular effects. In this study, we determined the acute effects of hypoglycemia on cardiovascular autonomic control. Seventeen healthy volunteers were exposed to experimental hypoglycemia (2.8 mmol/L) for 120 min. Cardiac vagal baroreflex functio...
متن کاملCardiovascular baroreflex sensitivity attenuates by cisplatin-induced toxicity in rats
Introduction: Cisplatin (CP) therapy may disturb cardiovascular system control. The objective of this study was to find baroreflex sensitivity (BRS) in CP-induced nephrotoxicity in rats. Materials and Methods: Eighteen male and female Wistar rats were randomly assigned to two groups treated with CP (2.5 mg/kg/day) and the vehicle, for five consecutive days, and then were subjected to surgical ...

متن کاملRelationship between spontaneous sympathetic baroreflex sensitivity and cardiac baroreflex sensitivity in healthy young individuals.
Low baroreflex sensitivity (BRS) is associated with elevated cardiovascular risk. However, the evidence is based primarily on measurements of cardiac BRS. It cannot be assumed that cardiac or sympathetic BRS alone represent a true reflection of baroreflex control of blood pressure. The aim of this study was to examine the relationship between spontaneous sympathetic and cardiac BRS in healthy, ...
