This is referred to as p-pulmonale since lung disease can cause severe right heart strain and right atrial enlargement. Thus, the P wave height becomes larger. The ECG criteria for diagnosing ...

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 ...

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 ...

ECG plays an important role in detection of several stroke risk factors/predictors including atrial fibrillation and left ventricular hypertrophy; both are components of the Framingham Stroke Risk ...

including AF and atrial remodeling and/or enlargement, play a role in many cases of SCD. 5,6 It is possible that such cases of SCD could be avoided using electrocardiogram (ECG) for early ...

Background: Atrial function is an integral part of cardiac function that is often neglected. The presence of left ventricule hypertrophy (LVH) due to arterial hypertension may impair atrial function.

A significant and progressive increase in aortic, left and right atrial ... of sudden cardiac death and a normal ECG presented a maximal wall thickness >14 mm. Established upper limits for ...
