In approximately 10% of infarctpatients, atrial infarct is suspected. An atrial infarct can manifest itself in atrial rhytmdisturbances: atrial fibrillation / atrial rhythm. Because the atria are hemodynamically of minor importance, the consequences of an atrial infarct are limited (and therfore often missed!). | In approximately 10% of infarctpatients, atrial infarct is suspected.

On the ECG, an atrial infarct manifests by | On the ECG, an atrial infarct manifests by rhythm changes and/or change of the [[PTa segment|P-Ta segment]] (sometimes called PTA (''P'' - ''a''triale ''T'') segment or PR or PQ or PTp (''P'' - ''T'' wave of ''P'' wave) segment)<cite>Abildskov</cite>. This is the part between the end of the P wave and the Q. The ST segment indicates an infarct in the ventricle, the P-Ta segment indicates an infarct in the atria. | ||
