Role of the autonomic nervous system in the development of cardiac arrhythmias in cats with acute myocardial ischemia receiving thyroliberin.
The role of the autonomic nervous system in the development of ischemic cardiac arrhythmias was studied in acute experiments on cats receiving thyrotropin-releasing hormone. Bilateral vagotomy attenuated, while bilateral transection of cardiac branches of the stellate ganglia completely abolished the antiarrhythmic effect of thyrotropin-releasing hormone.
