The sensitivity of all ECG criteria improves considerably when, apart from LVM+, the clinical evidence of LVH is also entered in the definition of LVH. The more certain the cardiologists were about the presence of LVH, the better the ECG performs. The additional Sokolow-Lyon criterion (SV3R + RV7) performs best for all reference standards.

Methods and Results. Incident stroke, myocardial infarction, cardiovascular death, the composite of these outcomes, and all‐cause mortality were examined in relation to the presence of on‐treatment ECG LVH by Cornell product and/or Sokolow‐Lyon voltage during a mean of 4.8±0.9 years follow‐up in 9193 patients with hypertension randomized to losartan‐ or atenolol‐based regimens.

In the additional analyses, we used two classifications regarding Cornell voltage and Sokolow-Lyon voltage for ECG-based LVH. All statistical analyses were performed by physicians (YS and TK) using JMP V.15 (SAS Institute, Cary, North Carolina, USA). All reported p values were two tailed, and the level of statistical significance was set at p<0.05.

Finally, the authors were unable to explore a purely manual or automated approach to ECG analysis and to test newer ECG criteria for LVH as only variables related to the Sokolow-Lyon and Cornell approaches were measured. 43-45 On the other hand, the Sokolow-Lyon and Cornell methods are also the ones traditionally endorsed by guidelines. 10

Sokolow-Lyon and sex-specific Cornell voltage criteria are used most commonly (2,3). Moreover, the product of QRS duration and voltage based on the Sokolow-Lyon and Cornell criteria for detecting LVH has shown more accurately than the voltage criteria alone (4,5). Nevertheless, ECG-derived LVH has been associated with

Left ventricular mass index by echo was the standard for diagnosing LVH. The closest ECG to the time of the echo was chosen for the analysis. Four ECG criteria (Cornell, Sokolow-Lyon, R aVL, R lead 1) were compared to the new Peguero-Lo Presti (PLP) criteria. The PLP criterion was the deepest S wave in any lead plus the S wave amplitude in V4.

In order to assess this ECG for LVH criteria, we need to look at leads V1, aVL, V5, and V6. Evaluating the Sokolow and Lyon criteria, we see that the S wave in lead V1 is approximately 30 mm and the R wave in lead V5 is approximately 21 mm; the sum of those two values is 51 mm, which is greater than 35 mm and meets one of the criteria for LVH.

For instance, Sokolow et al developed Sokolow voltage to detect LVH in 1949 for the first time and it was widely used in the past. 7 Lyon and Rappaport developed the method successively. Sokolow-Lyon (SL) index is a classical approach to define LVH, and it calculates the sum of QRS voltage of S wave in V1 and R wave in V5 or V6.

Left ventricular mass index by echo was the standard for diagnosing LVH. The closest ECG to the time of the echo was chosen for the analysis. Four ECG criteria (Cornell, Sokolow-Lyon, R aVL, R lead 1) were compared to the new Peguero-Lo Presti (PLP) criteria. The PLP criterion was the deepest S wave in any lead plus the S wave amplitude in V4.
