When left atrial enlargement occurs, it takes longer for cardiac action potentials to travel through the atrial myocardium; thus, the P wave also lengthens. Therefore, the criteria for diagnosing ...

When right atrial enlargement occurs, it does not take longer for cardiac action potentials to travel through the atrial myocardium (similar to left atrial enlargement). However, the amplitude of ...

Left-ventricular, right-ventricular and right-atrial size and systolic function were normal on echocardiography; left-ventricular ejection fraction was 60% and mild left-ventricular hypertrophy ...

Lipomatous hypertrophy of the atrial septum (LHAS) was diagnosed on the basis of the typical morphology and location. LHAS is a benign hyperplasia of lipocytes in the atrial septum (more exactly ...

In addition, echocardiographic variables, such left atrial enlargement, left ventricular wall thickness, and impaired left ventricular systolic dysfunction are also risk factors for developing the ...

regression of left atrial hypertrophy, or improved intra-atrial conduction, none of which is measurable by echocardiography or the surface ECG. Weight loss produced a dramatic decrease in the ...

In the presence of heart failure or hypertension with LV hypertrophy and diastolic dysfunction, the intra-atrial pressure is increased. The resulting activation of atrial stretch receptors induces ...
