| Negative on both arms and positive on left leg |

Term
|
Definition
| All the limb leads are considered "negative" so these are considered "positive" |

Term
|
Definition
| Current flows across the heart; positive deflection because it is going from right to left |
|
|
Term
|
Definition
| The current flow most closely simulates the electrical activity of the heart; current flows down and to the left; large positive deflection because it closely matches natural flow |
|
|
Term
|
Definition
| Positive deflection because the current is flowing down (which the heart naturally does) but not as large because it isn't flowing from right to left, its just flowing down |
|
|
Term
|
Definition
| Opposite of the heart therefore negative deflection; current flows up and to the right instead of down and to the left |
|
|
Term
|
Definition
| Current flows up and to the left when the heart flows down and to the left; this is exactly perpendicular to the heart's natural flow so it is isoelectric and there isn't really any net deflection |
|
|
Term
|
Definition
| Combination of Lead II and III; should be in between the height of those two leads; Current flows down and slightly to the left |
