Key result
Atrial flutter was associated with low cardiac output in patients with intrinsic heart disease, and resting blood flow increased upon conversion to sinus rhythm.
Why the study?
What are the cardiocirculatory hemodynamic characteristics of atrial flutter compared to sinus rhythm?
Population

What are the cardiocirculatory hemodynamic characteristics of atrial flutter compared to sinus rhythm?
Atrial flutter is associated with reduced cardiac output in patients with underlying heart disease, which improves upon conversion to sinus rhythm.
Harvey et al. (1955) conducted an observational in Atrial flutter (n=12). Atrial flutter vs. Sinus rhythm and atrial fibrillation was evaluated on Cardiac output and lesser circulation pressures. Atrial flutter was associated with low cardiac output in patients with intrinsic heart disease, and resting blood flow increased upon conversion to sinus rhythm.
