Acute Coronary Artery Occlusion and Cardiac Sympathetic Afferent Nerve Activity

Abstract
Myelinated sympathetic afferent fibers with conduction velocities in the A.delta. [motor fibers to muscle spindles] range arising from receptors located within the [canine] left ventricle responded to acute coronary artery occlusion with an increase in activity of over 100% above control levels. The increase in afferent nerve activity was directly related to an increase in left ventricular segmental length produced by acute coronary artery occlusion.
