Abstract excerpt

Previous studies suggest that the beta2-adrenoceptor functions abnormally in patients with postural tachycardia syndrome (POTS) and may contribute to their altered hemodynamic profile. To test the hypothesis that the beta2-adrenoceptor response is decreased in POTS, we studied: (1) the arterial vasodilation response to the beta agonist, isoproterenol, and (2) the distribution of common polymorphisms (codons 16...
