Key result
Apical transverse motion was significantly higher in patients with non-ischaemic left bundle branch block (4.3 mm) compared to healthy volunteers (1.8 mm; P<0.001).
Why the study?
Does apical transverse motion (ATM) measured by tissue Doppler imaging accurately assess left ventricular asynchrony in patients with conduction delays?

Apical transverse motion may indicate asynchrony in non-ischaemic LBBB; hypothesis-generating and should not yet change practice.

Apical transverse motion is a novel, simple echocardiographic parameter that integrates regional and temporal function inhomogeneities to assess left ventricular asynchrony.
Voigt et al. (2008) conducted a cross-sectional in Left ventricular asynchrony (n=67). Non-ischaemic left bundle branch block (nLBBB) vs. Normal healthy volunteers (NORM) was evaluated on Median apical transverse motion (ATM) (p=<0.001). Apical transverse motion was significantly higher in patients with non-ischaemic left bundle branch block (4.3 mm) compared to healthy volunteers (1.8 mm; P<0.001).
