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

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