| Question | Answer |
| How many Big boxes = ? seconds | 5 Big box = 1 second |
| Junctional Rhythm | Junctional Rhythm: Firing happens at AV node - No P wave |
| Supraventricular | Supraventricular: The rhythm is firing above the ventricles producing - up right waveforms - if firing below then the waveforms would be biphasic??? |
| Deep Q wave | Deep Q wave: Acute ischaemic attack |
| Flat T wave | Flat T wave Happens before Acute ischaemic attack or Hypokalemia |
| If Flat T wave due to Hypokalemia... | T wave will be inverted every time |
| If Flat T wave due to Acute ischemic attack... | T wave will be inverted in leads 1, aVL, V5, V6 (L. Lateral Leads) |
| V1 is (-) or (+) - why | V1 is (-) - because on R. side of body - electricity is traveling away |
| V2 is (-) or (+) - why | V2 is (-) - sometimes (+) |
| aVR is (-) or (+) - why | aVR is (-) - on Upper R. side of body |
| RVH (Right Ventricular Hypertrophy) | aVR and V1 will be (+) |
| V1 and V2 - called what kind of leads - placed where | V1 and V2 - called Septal leads - 4th intercostal space - V1 on L. side sternum V2 on R. |
| V3 and V4 - called what kind of leads - placed where | V3 and V4 - Anterior leads - V3 is between V2 and V4 1/2 over rid - V4 5th intercostal space |
| V5 and V6 - called what kind of leads - placed where | V5 and V6 - Lateral leads (as well aVL, I) - 5th intercostal space |
| II, III, aVF - called what kind of leads | II, III, aVF - Inferior leads |
