Term
| Which direction does septal depolarization occur? |
|
Definition
| Septal depolarization occurs from left to right and also slightly downward |
|
|
Term
| Which direction does atrial depolarization occur? |
|
Definition
| Atrial depolarization occurs from right to left and downward. This results in a positive deflection in Lead I and Lead aVF. |
|
|
Term
| What does the T wave represent? |
|
Definition
| Ventrical Repolarization after contraction. |
|
|
Term
| Ventricle repolarization occurs in which direction with respect to the Epicardium and Endocardium? |
|
Definition
| Repolarization occurs from Outside In, or from the Epicardium to Endocardium. |
|
|
Term
| What is the PR Interval and how long does it last? |
|
Definition
| PR Interval represents the time for depolarization to travel from the SA node through the AV node and into the His-Perkinje network. Typically it lasts for 0.12 - 0.2 seconds. |
|
|
Term
| What does the QRS interval represent and how long does it last? |
|
Definition
| Represents the total time of ventricular contraction which lasts for 0.08 - 0.12 seconds. |
