title: [Changes in the indices of the atrial complex on a differentially amplified ECG in atrial infarct].
abstract: The atrial complex of differentially amplified ECG was examined in 19 patients with atrial infarction. The diagnosis of atrial infarction was based on the electrocardiographic features, and in 7 cases it was confirmed by postmortem examination. The electrocardiographic pattern was characterized by P-Q segment shift. Atrial infarction resulted in a decrease in the amplitude, the prolongation of atrial conduction time and the appearance of additional fragments in the atrial complex of differentially amplified ECG.
