found it, found it, found it.

attached screenshot of ECG from 07 Jan 26 after
severe Sepsis symptoms (red face blotches,
faint, sweating) clearly meets the Seameans'
criteria of LVH.

several other ECGs taken in the past 2 months
also meet this criteria.

    Update 2022: A retrospective study of 2184
     patients comparing a new ECG screening
    criterion for LVH called the Semeans’ Sign
    (presence of QRS complexes touching or
    overlapping in two contiguous precordial leads)
    found it was noninferior to both the
    Sokolow-Lyon criteria and Cornell criterion
    for men.
