The effect of adrenergic enhancement (stimulation of a stellate ganglion or administration of norepinephrine) on arrhythmias induced by ventricular overdrive ("overdirve excitation") was studied in dogs with complete atrioventricular block. The following results were obtained. (1) Adrenergic enhancement may lead to abnormal ventricular rhythms. (2) A brief(More)
Fast idioventricular rhythm was studied in dogs with and without recently-induced complete atrioventricular block. The following results were obtained. The fast idioventricular rhythm (1) has an average rate of 92 ± 7.7 beats/min, (2) is either intermittent or continuous, (3) originates from either ventricle, (4) is initiated suddenly by a beat that usually(More)
Electron tunneling through a double quantum dot molecule side attached to a quantum wire, in the Kondo regime, is studied. The mean-field finite-U slave-boson formalism is used to obtain the solution of the problem. We found conductance cancelations when the molecular energies of the side attached double quantum-dot cross the Fermi energy. We investigate(More)
In the present work, we investigate the electronic transport through a T-shape double quantum dot system coupled to two normal leads and to one superconducting lead. We explore the interplay between Kondo and Andreev states due to proximity effects. We find that Kondo resonance is modified by the Andreev bound states, which manifest through Fano(More)
