Factorsinfluencingoutcome of regional wall motion

Coronary occlusionresultedin significant regional wall motion

In two studiescausedworsening of wall motion abnormality in segments with resting wall motion abnormality

Factorscontributingto regional wall motion abnormalities

Ventricular pre - excitation caused by right - sided accessory pathwaysmay resultin abnormal ventricular wall motion

infarctionhas causedregional wall motion abnormalities

by coronary ischemia(passive) caused byregional wall motion abnormalities

Myocardial ischemia from decreased perfusion during stresscausesabnormalities in ventricular wall motion

ConclusionVentricular pre - excitation caused by right - sided accessory pathwaysmay resultin abnormal ventricular wall motion

Our stenosis ... severe enoughto causeischemic wall motion abnormalities

The potential for abnormal loading conditionsto causewall motion abnormalities

This is expectedto leadto wall motion abnormalities

since necrosis is not neededto causewall motion abnormalities

The abnormal activation of the left ventriclecan causewall motion abnormalities

These high stresses together with delayed electrical activation of the tissueleadto abnormal wall motion

a constant amplitude pressure perturbation to the arterycausesan arterial wall motion perturbation

cells no longer contractleadingto abnormal wall motion

a significant blockagecausingwall motion abnormalities

the left bundle branch block itselfcan causewall motion abnormalities

the blood streamcan leadto abnormalities in the wall motion or
