| Romhilt-Estes Criteria for Left Ventricular Hypertrophy |
The EBMcalc module Romhilt-Estes Criteria for Left Ventricular Hypertrophy is available in EBMcalc Complete Edition.
This calculator evaluates the following Clinical Criteria:
- Biggest R or S wave in the limb leads greater than or equal to 20 mm; or S wave in V1 or V2 greater than or equal to 30 mm; or R wave in V5 or V6 greater than or equal to 30 mm
- Left atrial involvement - terminal deflection of P wave in V1 is 1 box wide, and 1 box deep or more
- Left axis deviation - QRS axis is -30 degrees or more negative
- QRS duration greater than or equal to 0.09 second
- Intrinsicoid deflection in V5 and V6 greater than or equal to 0.05 second
- ST-T segment changes ("LV strain" = ST-T vector shifted opposite to QRS vector)
