Domienik-Karlowicz J, et al. - Researchers evaluated the current ECG diagnostic criteria of left ventricular hypertrophy (LVH) in a group of morbidly obese patients with a BMI of at least 35 kg/m² (mean age 38.6 ± 8.9 years, BMI 48.7 ± 9.0 kg/m²; 323 females, 106 males) with the intention of validating their previously proposed criteria. They found that only by RaVL of 7.5 mm, Cornell index of 12.5 mm, Cornell index × QRS duration of 1,125 mm × ms, and Romhilt–Estes score of 1, the diagnosis of LVH in morbidly obese patients was validated. Findings corroborated non-appropriateness of the currently used voltage-based ECG criteria for diagnosing LVH in morbidly obese patients.
