LAP estimation in atrial fibrillation (ASE 2025 Figure 8)

Version 2026.10.1

Multiparametric estimate of mean LAP in atrial fibrillation with a normal, indeterminate or elevated result. It does not use the sinus-rhythm algorithm and does not grade diastolic dysfunction.

Quick reference:↑ Diastolic function and filling pressures

Flowchart:

Applicability

Atrial fibrillation only. In sinus rhythm use the sinus-rhythm pathway.
Use average values from several cardiac cycles reflective of the average heart rate.
