4. The EKG Guy Videos
Overview
- Vectors represent electrical impulse created by cardiomyocytes
- Vectors = energy + direction of impulse
Resultant Vector & Electrical Axis
- Represents sum of vectors (electrical impulses) => mean electrical axis
- Each wave & segment on EKG represents sum of vectors as they pass an electrode
- Basics to calculate resultant vector:
- Vectors traveling in same direction => add
- Vectors traveling in opposite direction => subtract
- Vectors traveling at an angle to each other => [add or subtract] + [change direction]
