Remember. When the cell is depolarizing it is becoming more positive. So, a positive depolartization toward a positive lead will inscribe a POSITIVE deflection on the EKG paper. |

A depolarization that is PERFECTLY PERPENDICULAR to the lead will incribe an isoelectric (i.e. baseline) on the EKG. However, this is rare, and most of the time the EKG will be biphasic (which has a little upward and downward deflection that is close to isoelectric). |
