Eg. Livanis et al., DECREASED POSTMYOCARDIAL INFARCTION HEART-RATE-VARIABILITY AND CARDIAC DENERVATION ASSESSED BY METAIODOBENZYLGUANIDINE SCINTIGRAPHY, The American journal of cardiology, 79(4), 1997, pp. 482
Decreased heart rate variability, assessed 2 weeks after uncomplicated
acute myocardial infarction, is related to the extent of I-123-metaio
dobenzylguanidine-derived efferent sympathetic cardiac denervation. Th
is postinfarction cardiac denervation could be the substrate of reduce
d postinfarction heart rate variability.
