RESUMO
The relationship between chronotropic and inotropic components of cardiac reflexes were studied in cats using intravenous blood injections, occlusion of the abdominal aorta, pressing on eyeballs (Aschner maneuver), and occlusion of the carotid arteries. Inotropic reactions were characterized by the contractility index DPxHR/MSAP. Different reflexes were shown to be characterized by different ratio of chronotropic and inotropic components, in addition, heart rate and contractility were often altered in opposite directions.
