[Influence of the hypothalamus on cardiac activity after administration of adrenergic blockaders and cholinolytics].
In dogs with implanted hypothalamic electrodes, influences of separate blockade of alpha- and beta-adrenoreceptors, M- and H-cholinoreceptors on cardiac rhythm and ECG before, during and after stimulation of ventromedial and posterolateral structures of the hypothalamus, were studied. Adrenoblocking and cholinolytic agents affected the heart rate and the ECG as well as changed the cardiac response to stimulation of the hypothalamus.
