Anteroseptal leads

2021-02-11 · Anteroseptal MI on ECG usually is characterized by the presence of ST-elevations in V1-V3 leads acutely followed by the development of Q waves in V1-V3 precordial leads. Presence of Q-waves in these leads is classically referred to as an age-indeterminate anteroseptal infarct. ST elevation is present in the high lateral leads (I and aVL). There is reciprocal ST depression in the inferior leads (III and aVF). QS waves in the anteroseptal leads (V1-4) with poor R wave progression indicate prior anteroseptal infarction. This pattern suggests proximal LAD disease with an acute occlusion of the first diagonal branch (D1).

The pattern of precordial STE was thought to be suggestive of anteroseptal myocardial infarction because of progressive STE toward lead V3. Mar 16, 2015 ANTEROSEPTAL ST ELEVATION MYOCARDIAL INFARCTION AND NON- DOMINANT RIGHT CORONARY ARTERY LESION INVOLVING The diagnosis of STEMI should be made by a 12-lead ECG. Note the ST segment elevation in anteroseptal and high lateral leads (I, aVL, V1-V3) and vation suggestive of anteroseptal acute myocardial infarc- tion (AMI) that elevation on precordial leads V 1–3 and DII, DIII, aVF and recipro- cal changes in DI Aug 21, 2016 There is reciprocal ST-segment depression in leads II, III, aVF, and V6. In this case there is obvious ST-segment elevation in the anterior leads The current electrocardiographic (ECG) definition of anteroseptal acute myocardial infarction (AMI) is a Q wave or QS wave > 0.03 second in leads V1 to V3, with Precordial leads detect septal and anterior activity. Anterior leads. Anteroseptal or septal leads.

These are the changes found in an acute anteroseptal AMI with lateral extension.

This provides the basis of maintenance of AV synchrony.

• Q waves are present in the septal leads (V1-2). • There is also some subtle STE in I, aVL and V5, with reciprocal ST depression in lead III. • There are hyperacute (peaked ) T waves in V2-4. • These features indicate a hyperacute anteroseptal STEMI A patient is described who developed STE in leads V1–V5 secondary to occlusion of the right ventricular branch during stent angioplasty to the right coronary artery.
