Diastolic Function E/A Ratio Grading Calculator

Grade diastolic dysfunction from E/A ratio: Grade I (impaired relaxation E/A<1), Grade II (pseudonormal), Grade III (restrictive E/A>2).

Clinical Guidance

BMI is a screening measure of body size, not a direct measure of body fat. The standard WHO categories are underweight (<18.5), normal (18.5–24.9), overweight (25–29.9), and obese (≥30).

BMI can overestimate body fat in athletes with high muscle mass and underestimate it in older adults with low muscle mass. Interpret it alongside waist circumference and clinical context rather than as a standalone diagnosis.

How It Works

Grade diastolic dysfunction from E/A ratio: Grade I (impaired relaxation E/A<1), Grade II (pseudonormal), Grade III (restrictive E/A>2)

Each component has a specific meaning:

  • E/A ratio: Grade I — The e/a ratio: grade i recorded for the scenario being assessed.
  • Grade II — The grade ii recorded for the scenario being assessed.
  • Grade III — The grade iii recorded for the scenario being assessed.

Note: Interpret the e/a diastolic result against the thresholds and context described above.

How to Use

Enter the E/A ratio: Grade I, Grade II, Grade III for the scenario you are assessing. Grade diastolic dysfunction from E/A ratio: Grade I (impaired relaxation E/A<1), Grade II (pseudonormal), Grade III (restrictive E/A>2). Use the e/a diastolic result to inform your calculation.
