Discussion

Implication

Hypothesis-generating for AF hemodynamics; prospective validation needed before any clinical application.

Structured PICO

Population

13 patients with atrial fibrillation

Intervention

Measurement of ascending aortic pressure-flow relationships using the pressure gradient technique

Outcome

Relationships between phases of systole, ventricular filling time, and derived parameters of pressure and flow (pulse pressure, stroke volume, peak flow, stroke work, peak power)surrogate

In patients with atrial fibrillation, stroke volume correlates strongly with the duration of ejection and preejection period, and is influenced by the preceding RR intervals.
