Electrical Vectors
Vector Direction and SizePage 4
- A depolarization wave traveling downward is represented by a downward vector(a).
- A depolarization wave traveling upward is represented by an upward vector(b).
- Two cells depolarization in same direction are represented by the addition of two vectors(c).
- Two cells depolarization in opposite directions cancel out each other's vectors(d).
Mean Electrical VectorPage 5
- The mean electrical vector(a) represents the quality and direction of depolarization for a group depolarizing cells.
