An electrocardiographic pattern of infarction of the interventricular septum, extending from the anterior to the posterior aspect of the heart

QS- and QR-Pattern in Leads V 3 and V 4 in Absence of Myocardial Infarction: Electrocardiographic and Vectorcardiographic Study

“…This pattern has been described on numerous occasions:'27 7 31,40,33,29,36,37,42,8,1,41,32 (these references are in chronological order) and designated as anteroseptal,30' 7extensive infarction of septum involviing the anterior and posterior wall,29 anteroposterior," 42,7 and posteroinferior infarction. 8 In two of our cases with such an electrocardiographic pattern, which came to autopsy, there was an occlusion of the descending branch of the left coronary artery with involvement of the anterior wall, inferior half of the septum in both and part of the posterior wall in addition in the other case.…”

Prognosis and Treatment of Cardiac Infarction

“…In our experience the electrocardiographic location of the isehaemic area was diagnostic of severe infarction only when the record showed antero-posterior infarction (Roesler and Dressler, 1947) or when posterior infarction was associated with bundle-branch block or heart-block (Table III). The latter, if transitory, may not be of grave significance; all five patients in whom it ushered in cardiac infarction but disappeared after few hours or days survived the two-months period, and three are known to be still alive.…”

Clinical significance of R‐wave amplitude in lead V1 and inferobasal myocardial infarction in patients with inferior wall myocardial infarction

“…Their findings revealed interventricular septal necrosis extending from the anterior to the posterior regions. In some instances, there was concurrent myocardial necrosis in the adjacent septum (Roesler & Dressler, 1947).…”
