The Use of Emotional Regulation Strategies in Reducing Test Anxiety during Test-Taking

The Use of Emotional Regulation Strategies in Reducing Test Anxiety during Test-Taking E. AryanaKia J. Hassani, Ph.D. It is well known that the use of emotional regulation strategies can reduce negative emotional experiences including anxiety. However, does the use of such strategies while taking an exam result in reducing test anxiety? To answer this question a cluster sample of 3...

Previous Beat Ejection but Not Previous Beat Pressure Load

Previous beat contraction history, in which the performance of the left ventricle on any one beat is influenced by the mechanical events of the previous beat, may be important in the beat-to-beat regulation of left ventricular performance in the intact cardiovascular system. Prior studies of this phenomenon have established that mechanical events of the previous beat influence the function of t...

Instantaneous monitoring of heart beat dynamics during anesthesia and sedation

Coupling of spontaneous ventilation to heart beat during benzodiazepine sedation.

We have examined in eight male volunteers the effect of midazolam sedation on the relationship between timing of spontaneous ventilations and heart beat. On 2 study days, subjects received either midazolam 0.1 mg kg-1 or saline placebo while recordings were made of ECG and ventilatory impedance pneumography. We observed in all midazolam-treated subjects clear evidence of synchronous or non-sync...
