BSA — m²
E/e′ ratio (septal, lateral, average)
Mitral peak E divided by septal e′, lateral e′ and the average of both, in matching velocity units.
Quick reference:↑ Diastolic function and filling pressures
At least one e′ site is required; both are needed for the average.
Enter Mitral peak E velocity to calculate.
Quick tool: no study or demographics required. Values entered here are shared with other tools in this tab until New study.
