HAEMODYNAMIC CHANGES FOLLOWING SYMPATHECTOMY
The sympathetic denervated heart showed little chronotropic response to anaesthetic and surgical stimulation. On the contrary, the parasympathetic response was predominant. An episode of severe bradycardia occurred during endotracheal suctioning prior to extubation. The haemodynamic response to cardiac sympathetic denervation corresponded to the efferent effect of beta-receptor blockade.
