原始语种摘要: Congestive heart failure (CHF) is characterized by reduced heart rate variability. Although various methods to achieve parasympathetic withdrawal and sympathetic activation have been documented, stimulation of the vagal nerve (that is, vagal maneuvers) has not often been used to assess the autonomic impairment associated with disease progression in veterinary species. In this study, we investigated cardiac autonomic control in a naturally occurring canine model of mitral insufficiency by means of individual responses to oculocardiac reflex. Indices of heart rate variability were calculated from 5-min ECG tracings obtained before and after ocular compression. After compression, significant increases in the standard deviation of RR intervals, root mean square of the successive differences...
