Abstract
The authors carried out clinical and statistical studies about 161 patients with atrial fibrillation, paroxysmal tachycardia and W.P.W. syndrome. All patients have been in-patient in Maekawa Clinic of Kyoto University Hospital from 1949 to 1958. The exact mechanism of production of these arrhythmias is not clear ; theories have ascribed the main factor responsible for the arrhythmia of non-cardiac orignin to the unstable nervous system, to "vegetative Dystonie", or to autonomic disturbance, but there is little definite evidence against or for these theories. Especially, the authors studied clinically these lone or idiopathic arrhythmias from the point of view of the spinal sympathetic nervous regulation of the heart. And it may be concluded that pathogenetic origin of the lone arrhythmia is disturbance of spinal sympathetic control of the heart beat.
