When it comes to interpreting EKGs, I’ve always been a visual person. I tend to reconstruct the three leads and the main electrical vector in my head. Using Angular (actually my first Angular app), I’ve created a small tool to draw the main electrical axis. From this axis, the corresponding “heights” of the leads are calculated. It was actually quite fun to dive back into geometry and figure out all the formulas, producing the crossing points of all the lines.
