Heart rate and blood pressure biofeedback: II. A review and integration of recent theoretical models.

The theoretical models put forth separately by Bremer, Lang, and Schwartz to account for the data on biofeedback and cardiovascular responses are summarized and evaluated in light of recent empirical studies. Although each model makes some use of the idea that learning to control heart rate, particularly heart rate acceleration, is like motor skills learning, each model also emphasizes different sets of factors or variable. An attempted integration of these three models is presented.
