Atrial fibrillatory rate and risk of left atrial thrombus in atrial fibrillation

In atrial fibrillation (AF), a relation between electrocardiogram (ECG) fibrillatory wave amplitude and thrombus formation has been sought for long with conflicting results. In contrast, the possible relation between atrial fibrillatory rate obtained from the surface ECG and left atrial thrombus formation in patients with AF is unknown and was consequently evaluated in this study.One-hundred and twenty-five patients (mean age 64 +/- 12 years,...
