Selvester and Rubin developed quantitative electrocardiographic criteria to identify definite or probable emphysema in patients.
(A) P axis > +60° in the limb leads (I, II, III, aVF, aVR, aVL)
(B) R and S amplitudes <= 0.70 mV in limb leads
(C) R amplitude <= 0.70 mV in V6
(D) S in V4 >= R in V4
Definite emphysema - one or both of the following:
(1) A and B and C, or
(2) A and D
Probable emphysema - one or both of the following:
(1) A and B, or
(2) A and C
• 65% sensitive for the diagnosis of emphysema
• 95% specific for exclusion of emphysema in normal persons, in patients with congenital heart disease, and in patients with myocardial infarction.
