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 ...

Left atrial enlargement refers to dilation of the left atrium which occurs from multiple disease states that can chronically increase the left atrial pressure. These include congestive heart ...

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 ...

[29] P wave morphology, such as notching – a likely indicator of left atrial enlargement – was found to be associated with incident stroke. [41] Among several predictors of AF, P wave duration ...

For high-blood-pressure patients, preventing or reducing enlarged heart (left ventricular hypertrophy, LVH) reduces risk of atrial fibrillation (AF or afib), a life-threatening condition that can ...

An electrocardiogram showed atrial fibrillation, with large "f" waves, right-axis deviation anda 6-mm. R′ wave in Lead V 1 that was compatible with hypertrophy of the right ventricle.

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 ...
