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

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 Report A 29-year-old woman was admitted to the Gerontology Research Center in 1972.
