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!).

On the ECG, an atrial infarct manifests by rhythmchanges 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 P wave and the Q. The ST segment indicates an infarct in the ventricle, the P-Ta segment indicates an infarct in the atria.
