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

Assess Ebstein anomaly severity using cardiothoracic ratio (CTR) on chest X-ray. CTR >0.65 indicates severe cardiomegaly from massive RA/atrialized RV enlargement

Each component has a specific meaning:

  • Cardiothoracic ratio on chest X-ray — The cardiothoracic ratio on chest x-ray recorded for the scenario being assessed.

Note: Interpret the ebstein ctr result against the thresholds and context described above.

How to Use

Enter the cardiothoracic ratio on chest X-ray for the scenario you are assessing. Assess Ebstein anomaly severity using cardiothoracic ratio (CTR) on chest X-ray. CTR >0.65 indicates severe cardiomegaly from massive RA/atrialized RV enlargement. Use the ebstein ctr result to inform your calculation.
