Anatomical considerations and clinical interpretation of the 12-lead ECG in the prone position: a prospective multicentre study

ConclusionIn prone back position ECG, low QRS amplitude should not be misinterpreted as low voltage conditions, neither should Q waves and abnormal T waves are considered anteroseptal myocardial infarction. These changes can be explained by an increased impedance (due to interposing lung tissue) and by the increased distance between the electrodes to the centre of the heart.
