Peguero et al proposed a new ECG score for the diagnosis of left ventricular hypertrophy (LVH). The authors are from Columbia University and Mount Sinai Medical Center (Miami).
l Center (Miami).
Patient selection: adult (mean 54 +/- 17 in test and 68 +/- 15 in validation groups)
Parameters:
(1) amplitude of the deepest S wave in any lead in mV
(2) amplitude of the S wave in lead V4 in mV
(3) sex
score in mV =
= (amplitude of deepest S wave) + (amplitude in V4)
Sex
Score for LVH
female
>= 2.3 mV
male
>= 2.8 mV
Performance:
• The area under the ROC curve reported as 0.85.
Macfarlane et al commented that different cut-offs may be necessary for patients less than 40 years of age. In addition, they commneted that race may also need to be considered.
