Learned Control of Cardiac Rate and Cardiac Conduction in the Wolff-Parkinson-White Syndrome

Abstract
IT has been shown that normal men can be trained to slow, speed and cyclically slow and speed heart rate.1 2 3 4 Patients with premature ventricular contractions can be trained to decrease and to control them.5 Patients with chronic atrial fibrillation can be trained to change ventricular rate by the modification of vagal tone to the atrioventricular node.6 Our purpose in this study was to determine whether a patient with intermittent Wolff-Parkinson-White syndrome can learn to control heart rate and also to modify the pathway of cardiac conduction.Case ReportA 29-year-old woman was admitted to the Gerontology Research Center in 1972. . . .
