[Correlation between chest radiography and the echocardiogram to evaluate cardiomegaly in patients with systemic arterial hypertension].

Unlabelled: The chest radiography is used routinely by the clinician as a tool in the scan of patients with systemic arterial hypertension (SAH) to evaluate the dimensions of the heart. However the highest reported sensitivity for the evaluation of heart growth with this method is 77.3% in contrast to the transthoracic echocardiogram (TTE) that reaches between 90 to 100%.
