Conclusions

Echocardiographically derived LPS values were modestly dependent on angle of insonation and target depth in this pediatric population. Normal strain ranges derived from standard apical images should not be applied to strain derived from sub-costal images, off-axis apical imaging, or applications in which a standard window cannot be defined.

Importante saber, mas varia pouco.

Só com muito estresse físico

This method is cost effective, safe and free of non-ionizing radiation . Stress Echo is one of the most important tools for assessing myocardial ischemia and viable myocardia , in addition being easy to use at the bedside
