Echocardiographic Assessment of the Right Ventricle in Healthy Subjects During Stress Test in the Mexican Population

Echocardiographic Assessment of the Right Ventricle in Healthy Subjects During Stress Test in the Mexican Population

The echocardiographic indices of the right ventricle function vary significantly with demographic and anthropometric of each population factors and are associated with poor prognosis in several cardiovascular diseases.

This study aims to investigate exercise-induced changes in echocardiographic indices of the right ventricle function in healthy volunteers and establish the reference values to the Mexican population.
