Journal of Applied Physiology, 1982
It was hypothesized that the chronotropic response to intrathoracic pressure changes generated by cough may provide a reliable and rapid index of the cardioacceleratory capacity, a complex reflex response important for survival. In 27 adults in the supine position we measured the heart rate response following three forceful coughs performed over a 3-s

The Response of Debtors to Rate Changes
SSRN Electronic JournalHow borrowers respond to future changes in the interest rate on their debt matters for the transmission of monetary policy and for household financial stability. Combining bank data, a letter RCT, and a survey, we study this question in the context of the German mortgage market, where since 2022 borrowers have faced high interest rates when their rate ...

Concepts of rate responsive pacing
IEEE Engineering in Medicine and Biology Magazine, 1990Various concepts for measuring (by means of biosensors incorporated into pacemakers) biologic parameters to determine the appropriate pacing rate are reviewed. They are pH, stimulus-to-T-wave interval, blood temperature, intercardiac blood pressure change, venous oxygen saturation, intercardiac impedance (stroke volume, ejection rate, preejection ...

Response Rate and Conditioned Suppression
Psychological Reports, 1966Two experiments are reported in which a yoked-box design permitted variation of response rate while reinforcement frequency was controlled. In both studies, rats responding at high rates showed more conditioned suppression than their partners responding at lower rates.

Rate-Responsive Cardiac Pacemakers
AACN Advanced Critical Care, 1991Pacemaker technology continues to advance in the direction of restoring a normal hemodynamic response under varying physiologic conditions. Rate-responsive pacemakers meet this challenge by adjusting the pacing rate in response to a sensed physiologic variable other than sinus node activity.

Heart Rate Response to Racquetball
The Physician and Sportsmedicine, 1981In brief: Nine male racquetball players were monitored during matches with Opponents of equal, stronger, and weaker ability, and heart rate response and intensity of play were determined. The highest heart rate and percent intensity occurred when the monitored player was weaker than his opponent and the lowest occurred when he was stronger than the ...

Rate‐Drop Response Programming
Pacing and Clinical Electrophysiology, 1997Effective programming of the rate‐drop response algorithm requires careful attention to the heart rate and blood pressure responses seen during diagnostic tilt testing. In order to undertake effective programming, additional tilt testing procedures may be necessary, and it is vital that the protocol should be identical on each occasion and very careful

Random Fluctuations of Response Rate
Psychometrika, 1962A simple model for fluctuating interresponse times is developed and studied. It involves a mechanism that generates regularly spaced excitations, each of which can trigger off a response after a random delay. The excitations are not observable, but their periodicity is reflected in a regular patterning of responses.
