Heart rate variability and familial amyloidosis.
A 32-year-old man with family history of amyloidosis was admitted to the hospital because of orthostatic hypotension. An echocardiogram was suggestive for cardiac amyloidosis. Heart rate variability analysis, performed on 24-h Holter monitoring, showed markedly low values in both frequency and time domain, reflecting a severe autonomic nervous system dysfunction.
