May alter digital pulse interpretation in research settings; leaves open any clinical relevance for vasodilator use.
Does sublingual nitroglycerin alter digital circulation and pulse wave characteristics in humans?
Sublingual nitroglycerin produces disproportionate dilatation of the arterial system, affecting the dicrotic notch of the pulse wave, suggesting greater regional vasodilatation near the heart.
George E. Burch (1986) studied this question.
