Abstract:A hemodynamic and renal study was carried out on eight pacemaker‐treated patients with complete heart block. At the time of study the patients were normotensive and well compensated. Cardiac output, brachial arterial pressure, inulin‐ and PAH‐clearances as well as the excretion of electrolytes were determined on two or three selected heart rate levels between 45–118 for each patient during four to six 20‐minute periods. A change of the ventricular rate from low to high level gave a significant decrease of stro… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
