Echocardiographic indicators of LVH according to 2015 recommendations for cardiac chamber quantification by echocardiography in adults: an update from the ASE and the EACVI [32]

LVM (by the Penn convention)LVMI in LVH

Devereux formula for LVM:

LVM = 1.04 [(LVEDd + IVSd + PWT)3 – (LVEDd)3] – 13.6

LVMI = LVM/BSA

females > 95 g/m2

males > 115 g/m2

Anteroposterior LA dimensionLA in LVH
-LA > 40 mm

PWT: posterior wall thickness; -: none
