EKG (Do Not Edit This Line) STE localize better than ST depressions/T wave inversions. Anterior (V1-V4); a ... Ventricular septal defect . Occurs in 1-3% of post MI patients, 1-10 days post MI. Causes 5% peri-infarct deaths. If anterior MI, VSD usually in apical septum. If inferior MI, defect located on basal inferior septum (worse outcome/more ...

EKG and Interpretation. Coronary Circulation. Branch off ascending aorta-Left coronary artery- supplies blood to the anterior and lateral wall of the left ventricle. Left anterior descending supplies oxygenated blood to the walls of the left ventricle and the anterior part of the septum.

The 12 lead EKG is also broken into territories: inferior, anterior, septal, & lateral. The posterior territory is not directly seen on the ECG (but there are tricks to find it, including looking at the ECG “backwards” or doing a “right-sided EKG”).

The septal leads (front of the heart) reflect a posterior event (back of the heart) in the same way that inferior / lateral ones do, but there are no true “posterior” leads on an EKG. The way you see the posterior heart is via a right-sided EKG (place V4 on patient’s back), or by looking at …

The septal leads also reflect activity in the posterior of the heart, and there are special EKG changes that reflect that: if a septal MI would show ST elevations (at first) in V1 and V2, then those same leads would show ST depression in a posterior MI, due to an EKG effect called “reciprocity” – more on that below.
