Septal infarcts are associated with diagnostic Q waves in V1and V2. While a QS pattern in V1-2 usually is associated with a septal infarct, it can occur with anatomic changes (vertical axis) due to lung disease or LVH and with intraventricular conduction defects such as LAFB, LBBB, and WPW or with hypertrophic cardiomyopathy.

Right bundle-branch block dependent Q waves may arise during the acute stage of an anterior infarct suggesting, fallaciously, that an acute extension has occurred, or during the chronic stage, leading to the erroneous supposition that a new infarct had developed. 2012-05-01 · False positive late enhancement: septal perforator in a 64-year-old woman. Basal short-axis (A) and two-chamber long-axis (B) images show linear region of increased midwall signal intensity. This has a tapered appearance with a similar signal intensity to that of the blood pool. Anteroseptal myocardial infarction is defined by the presence of electrocardiographic Q-waves limited to precordial leads V(1) to V(2), V(3), or V(4). We sought to determine whether this term is appropriate by correlating electrocardiographic, echocardiographic, and angiographic findings.
It is different from an acute myocardial infarction or heart attack, as those are caused by a complete deprivation of blood It was also apparent that right bundle-branch block shifted the electrical location of the infarct towards the right, and made it look much larger. Right bundle-branch block dependent Q waves may arise during the acute stage of an anterior infarct suggesting, fallaciously, that an acute extension has occurred, or during the chronic stage, leading to the erroneous supposition that a new infarct had developed. 2012-05-01 · False positive late enhancement: septal perforator in a 64-year-old woman.

An anteroseptal infarct is a heart attack in the front of the heart. Old and probable mean exactly what they say. The part of the wave called the Q wave is apparently slightly longer than normal and the ST segment of the wave has an anomaly.
