    Abstract:
    In nine patients with syndrome of ventricular over-excitation of intracavitary electrocardiographic investigation was carried out, including recording of Hiss bundle potentials, right and left auricle, programmed, increment and high frequent stimulations. The anatomic characteristic of the additional connection, on the base of the deformation of QRS-complex and the type of the retrograde conduction in case of ventricular stimulation showed that the connection started from the right auricle. In five--it terminates in the left ventricle, and in four--in the right. In the majority of the patients it is with an effective refractory phase under 300 msec., corresponding to the electrophysiological characteristic of a direct connection between auricles and ventricles. The problem of the origination of the phenomenon of circling excitation in the patients with the syndrome of ventricular overexcitation is discussed.
