Are current voltage-based ECG criteria appropriate for diagnosing left ventricular hypertrophy in morbidly and super-morbidly obese patients?
Current voltage-based ECG criteria are inadequate for diagnosing left ventricular hypertrophy in morbidly and super-morbidly obese patients, highlighting the need for modified cutoff values.
Voltage criteria lack utility for LVH diagnosis in morbid obesity; supports validation of adjusted thresholds before clinical adoption.
BACKGROUND: Current diagnostic ECG criteria of left ventricular hypertrophy in obese patients are still lacking. OBJECTIVE: To assess the current ECG diagnostic criteria of LVH, and to validate our previously proposed criteria in a group of patients with morbid obesity. METHODS: ; 323 females, 106 males) were included. RESULTS: The diagnosis of LVH in MOPs was confirmed 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. None of the criteria proposed to date is appropriate in super-morbidly obese patients. CONCLUSION: Our study confirmed that none of the currently used voltage-based ECG criteria is appropriate for diagnosing LVH in morbidly obese patients. Further studies are required.

Domienik‐Karłowicz et al. (2018) conducted an observational in Morbid and super-morbid obesity (n=429). Voltage-based ECG criteria was evaluated on Diagnosis of left ventricular hypertrophy. Currently used voltage-based ECG criteria are not appropriate for diagnosing left ventricular hypertrophy in morbidly and super-morbidly obese patients.
