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 ...

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 ...

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 ...

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.

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 ...

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 ...
