Note that left atrial enlargement is not able to be diagnosed in the presence of atrial fibrillation because this rhythm is defined by erratic atrial activity and no visible P wave on the ECG.

P area and signal-averaged P wave late atrial potential are strong predictors of AF incidence and possibly of stroke incidence. ECG left ventricular hypertrophy is strongly associated with stroke ...

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 ...

When right atrial enlargement occurs, it does not take longer for cardiac action potentials to travel through the atrial myocardium (similar to left atrial ... The ECG criteria for diagnosing ...

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.
