1. What is the correct name for ECG?
Electrocardiogram
2. What is an ECG?
A test to show the electrical activity in the heart and weather or not it normal. There it two types a 3 lead ECG or 12 lead ECG.
3. What is a Three Lead ECG?
A three Lead ECG shows one angle of the heart. Using four leads one on each wrist and one on each ankle.
4. What does RIDE YOUR GREEN BIKE stand for?
The positioning of the four leads on a three lead ECG. Red, Yellow, Green and Black. Going Right wrist, Left wrist and Left ankle, Right ankle.
5. What is a 12 Lead ECG?
• This shows many different angles of the heart using 10 leads. There is the ones of the wrist and ankle, also 6 on the chest. The positioning of the chest lead are:
• V1 = 4th intercostal space to the right.
• V2 = 4th intercostal space to the left.
• V3 = Midway between V2 and V4.
• V4 = 5th intercostal space, midclavicular line
• V5 = Anterior axillary line, in-line with V4.
• V6 = Midaxillary line, in-line with V4 and V5.
6. What is Eindhoen's Triangle?
• How lead 1,2 and 3 work.
• Lead 1 is the travelling of the electrons through the heart. Starting on the Left arm and travelling to the Right arm.
• Lead 2 is the electrons travelling from the left foot to the right arm.
• Lead 3 is the electrons from the left foot to the left arm.
7. Augmented Vector?
• How lead AVR, AVL and AVF work.
• AVR = the travelling of electrons from Right arm to left chest area. Normally resulting in a negative ECG.
• AVL = the travelling of electrons from the Left arm to right chest area.
• AVF = thr travelling of electrons from the left foot to the mid chest area.
8. How do you group a 12 lead ECG?
• Lead 2, 3 and AVF = Inferior Group
• Lead 1 and AVL = High Lateral
• V1,2,3,and 4 = Anterior Group
• V5 and 6 = Low Lateral
• Ignore AVR
9. What are the different waves called and what do the mean?
• P wave- Is depolarization of the Atrium in respones to the AV Node firing.
• Q wave - Is depolarization of the Septum.
• R and S wave- The depolarization of the Verticals.
• T wave- Is the heart repolarization.
10. What is this ECG Rhythm?
Normal Sinus Rhythm
11. What is this ECG Rhythm?
• Normal P,Q,R,S and T wave, however the heart rate is very slow.
12. What is this ECG Rhythm?
• Sinus Tachycardia
• Normal P,Q,R,S and T but the heart rate is very fast.
13. What is this ECG Rhythm?
• This means the P wave is firing below the junction of the AV Node
14. What is this ECG Rhythm?
• Atrial Fibrillation
• The heart is just doing whatever it wants too. If this is an on going condition it is fine, however if it is the first time needs to go hospital.
15. What is this ECG Rhythm?
• 1st Degree AV Block.
• This is where the P wave is firing and not giving chance for the heart to rest. It can sometimes mean the P wave is on the T wave.
16. What is this ECG Rhythm?
• 2nd Degree AV Block, type 1.
• Also known as "Wencheback".
• This will look like a normal P wave and QRS, then the P wave will get further away from the QRS. It will then miss a wave and as the P wave won't get through.
17. What is this ECG Rhythm?
• 2nd Degree AV Block, Type 2.
• There will be no Rhythm some P wave just won't get through.
18. What is this ECG Rhythm?
• 3rd Degree AV Block.
• There is no P wave but the heart continues to go.
19. What is this ECG Rhythm?
• Ventricular Fibrillation.
• Very Fussy
20. What is this ECG Rhythm?
• Ventricular Tachycardia.
• Very Tidy
21. What is this ECG Rhythm?
• Normal rhythm with a Pacemaker.
• The spike down it the pacemaker firing.
22. What is PEA?
• Pulseless Electrical Activity,
• This will appear as a normal ECG but there will be no Pulse.
23. The ratio for Vertical axis is?
• 1 small square = 1mm (0.1mv)
• 1 Large Square = 5mm (0.5mv)
• 2 Large Square = 1mv
24. The ratio for Horizontal axis is?
• 1 small square = .04 seconds (40m seconds)
• 1 Large square = .2 seconds (200m seconds)
• 5 Large square = 1 second ( 1000m seconds)
25. The 10 steps to reading an ECG?
• 1) QRS rate? (Is it normal, between 60-100 bpm)
• 2) Is the QRS regular, irregular or regular irrefular?
• 3)QRS Duration? (Is it normal, 120ms or lower, i.e. 3 small squares max)
• 4)Are P wave present?
• 5) Is there a P wave to every QRS?
• 6) Is the PR interval normal, between 120ms and 200ms and is it constant?
• 7) Are the T waves the correct way up and normal shape?
• 8) Is the ST segment isoelectric?
• 9) Any Pattens in any groups
• 10) Evaluate it all together.
26. What dose a wrong way up T wave mean?
