The aV limb leads in the diagnosis of ventricular strain

Left-Ventricular Hypertrophy in the Elderly: Unreliability of ECG Criteria in 477 Subjects Aged 65 Years or More

“…These results are at variance with those of others, showing a surprisingly high sensitivity of criteria based on the Sokolow-Lyon voltages [10][11][12][13][14], limb voltage [11,18,19], the Cornell index [20. 21] or the Romhilt-Estes score [15,16].…”

“…The Romhilt-Estes point-score system (ta ble 1) was positive when a score of 4 or more was reached [15][16], LVH was also diagnosed when the sum of net positivity in D| plus the net negativity in D3 was at least 17 mm (Lewis index) [17], or when the R voltage was over 11 mm in aVL [18,19], The Cornell index was calculated by adding the S voltage in V, and R voltage in aVL; according to the suggestions of Casale et al [20. 21], its cutoff values for the diagnosis of LVH were different in males (>28 mm) and females (>22 mm).…”

ECG left ventricular hypertrophy is a stronger risk factor for incident cardiovascular events in women than in men in the general population

“…Minnesota-coding was performed from printed ECGs at the Institute of Cardiology, Kaunas Medical Academy, Lithuania. LVH criteria were selected from the literature (Table 1) [7,[13][14][15][16][17][18][19][20][21][22].…”

AHA/ACCF/HRS Recommendations for the Standardization and Interpretation of the Electrocardiogram

“…The ECG criteria for LVH shown in Table 1 have evolved over the years. [65][66][67][68][69][70][71][72][73][74][75][76][77][78] Criteria were originally based on R and S amplitudes in standard limb leads I and III, using clinical and autopsy data as reference standards. 4 -6 (Amplitudes of ECG complexes are referred to in millimeters, rather than millivolts.…”
