title: [Atrial electrocardiotopogram in acute myocardial infarct complicated by heart failure].
abstract: Atrial electrocardiotopography is shown to be a fairly informative non-invasive method for both the detection of heart failure and the assessment of its severity. Its findings were verified by conventional invasive and non-invasive procedures. Moderate left-ventricular heart failure was only associated with increased total left-atrial electrical activity, while marked heart failure also involved an expanded negative P wave projection zone and a greater total magnitude of right-atrial potentials.
