Hypothesis-generating for beta-blockade in tetralogy of Fallot; leaves open randomized confirmation before any practice consideration.
Does pronethalol improve arterial oxygen saturation during exercise in patients with Fallot's tetralogy?
Beta-blockade with pronethalol reduces dynamic right ventricular outflow tract obstruction and improves arterial oxygen saturation during exercise in patients with Fallot's tetralogy, suggesting a role in managing cyanotic attacks.
Honey et al. (1964) studied this question.
