EKG Basics
Cards in this deck (16)
- 1How many Big boxes = ? seconds5 Big box = 1 second
- 2Junctional RhythmJunctional Rhythm:
Firing happens at AV node
- No P wave - 3SupraventricularSupraventricular:
The rhythm is firing above the ventricles producing
- up right waveforms
- if firing below then the waveforms would be biphasic??? - 4Deep Q waveDeep Q wave:
Acute ischaemic attack - 5Flat T waveFlat T wave
Happens before Acute ischaemic attack or Hypokalemia - 6If Flat T wave due to Hypokalemia...T wave will be inverted every time
- 7If Flat T wave due to Acute ischemic attack...T wave will be inverted in leads 1, aVL, V5, V6 (L. Lateral Leads)
- 8V1 is (-) or (+) - whyV1 is (-)
- because on R. side of body
- electricity is traveling away - 9V2 is (-) or (+) - whyV2 is (-)
- sometimes (+) - 10aVR is (-) or (+) - whyaVR is (-)
- on Upper R. side of body - 11RVH (Right Ventricular Hypertrophy)aVR and V1 will be (+)
- 12V1 and V2 - called what kind of leads - placed whereV1 and V2
- called Septal leads
- 4th intercostal space
- V1 on L. side sternum V2 on R. - 13V3 and V4 - called what kind of leads - placed whereV3 and V4
- Anterior leads
- V3 is between V2 and V4 1/2 over rid
- V4 5th intercostal space - 14V5 and V6 - called what kind of leads - placed whereV5 and V6
- Lateral leads (as well aVL, I)
- 5th intercostal space - 15II, III, aVF - called what kind of leadsII, III, aVF
- Inferior leads - 16—
