WebWhen the inotropic state increases, end-systolic volume decreases so that stroke volume can be maintained and allowed to increase despite reduced time for ventricular filling and elevated arterial pressure. Factors Regulating Inotropy. The most important mechanism regulating inotropy is the autonomic nerves. Webneurotransmitter actions, the chronotropic state of the heart can be modulated by a variety of neuropeptides, such as neuropeptide Y, that appear to be colocalized with conventional neurotransmitters in autonomic terminals (Kukanova Mravec, 2006; Shine et al., 1994).

Webchronotropic response: A change of heart rate over time in response to stimuli—e.g., exercise, manual labour, sexual activity. WebSince amiodarone is a negative chronotropic drug, its purpose is to decrease the electrical impulses coming from the AV node as well. So, when a client is experiencing a detrimental rhythm, like ventricular fibrillation, the priority is to get them out of that state by providing chemical cardioversion in the form of Amiodarone or antidysrhythmics.
