In approximately 10% of | 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 chnage of the P-Ta segment (sometimes calledPTA (''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. | On the ECG, an atrial infarct manifests by rhythmchanges and/or chnage of the P-Ta segment (sometimes calledPTA (''P'' - ''a''triale ''T'') segment or PR or PQ or PTp (''P'' - ''T'' wave of ''P'' wave) segment)<cite>Abildskov</cite>.
