In the '''Romhilt-Estes Score''' LVH is ''likely'' with 4 or more points. LVH is ''present'' with 5 or more points: | |||
* Amplitude of R or S wave in limb leads >2.0 mV, or S wave in V1 or V2 >3.0 mV, or R wave in V5 or V6 >3.0 mV = 3 points. | |||
* ST-segment changes with or without digitalis = 1 or 2 points, respectively. | |||
* LA abnormality = 3 points. | |||
* Left-axis deviation -30° or more = 2 points. | |||
* QRS duration >90 ms = 1 point. | |||
* Intrinsicoid deflection in V5 or V6 = 0.05 to 0.07 s. | |||
