| Question | Answer |
| Sinotrial Node Inherent Rate | 60-100 BPM |
| Atrioventricular Junction Inherent Rate | 40-60 BPM |
| Purkinje Fibers Inherent Rate | 20-40 BPM |
| Lead I Placements | Left arm = +, Right arm = - |
| Lead II Placement | Left foot = +, Right arm = - |
| Lead III Placement | Left foot = +, Left arm = - |
| P Wave | Atrial Depolarization |
| PR Interval | Spread of impulse through AV node, bundle of His, right and left bundle branches, and Purkinje fibers |
| QRS complex | Spread of electrical impulse through the ventricles (Ventricle depolarization) |
| T Wave | Ventricle repolarization |
| QT Interval | Total ventricular activity, from ventricular depolarization to repolarization |
| Normal P Wave Characteristics | Smooth and rounded, no more than 2.5mm in height, no more than 0.11 sec in duration, positive leads I, II, aVF, and V2 through V6 |
| Normal PRI Characteristics | 0.12 to 0.20 sec, Shortens as heart rate increases, Lengthens as HR decreases |
| QRS complex Normal Duration | 0.06-0.10 sec |
| Wide QRS Complex may indicate | incomplete or complete bundle branch block |
| ST Segment is elevated if it is | more than 1 mm in a limb lead, more than 2 mm in a chest lead |
| Normal T Wave Characteristics | slightly asymmetric, 5mm or less in height in limb lead or 10mm in chest lead, 0.5 mm or more in height in leads I and II |
| Peaked T Wave may be a sign of | Hyperkalemia |
