In a double-blind study 8 healthy male subjects received 100 micrograms human atrial natriuretic facotr-(99-126) (hANF) and NaCl0.9% in random order on different days. Following hANF injection a significant increase in cardiac beat-to-beat variation was observed (4.65% vs 5.95%). This shows that in vivo human atrial natriuretic factor stimulates cardiac parasympathetic activity in man.
