the results indicate that earlier investigations of the distribution of chat in the heart provided a basically correct picture although the contribution of carat to the synthesis of ach measured had not been excluded , and confirm that chat is present throughout the heart , including the apical parts of the ventricles , however , the sino-atrio-ventricular gradient of chat distribution is steeper when the contribution of carat to the synthesis of ach is excluded .
