From: Echocardiography-based left ventricular mass estimation. How should we define hypertrophy?
Comparison between M-mode border measurement conventions. The Standard convention measures from leading to trailing edge in the septum and from leading to leading edge of the posterior wall. Penn criteria excludes echoes from parietal walls while ASE criteria measure leading to leading edge. (LVDd: Left Ventricular Diameter in Diastole).
