摘要: Abstract Objectives. This study evaluated the role of changes in heart rate, cardiac filling pressures and tissue atrial brain natriuretic peptides modulation their plasma levels a model failure. Background. Atrial constitute dual peptide system that regulates circulator homeostasis. Methods. The effects 1) acute ventricular pacing, 2) volume expansion, 3) expansion after 1 week continuous pacing on were compared eight dogs. examined 5 normal dogs (control group), 21 paced for (group 10 3 weeks 2). Results. Both increased (from 53 ± 41 to 263 143 pg/ml [mean SD], p Conclusions. respond differently rate pressures. Reduced failure may indicate reduced storage enhanced release, However, relatively modest change suggests elevated be mediated by mechanisms other than pressured.
