Where do you play the 1st lead
4th Intercostal Space, Right of sternum
Where do you play the 2nd Electrode
4th Intercostal Space, Left of sternum
Where do you play the 3rd Electrode
Midway between 2nd and 4th Electrode
Where do you play the 4th Electrode
5th intercostal space, mid clavicle line
Where do you play the 5th Electrode
Anterior Axillary line, Straight line from 4th Electrode
Where do you play the 6th Electrode
Mid Axillary line, in a straight line of 4 & 5th Electrode
Where do you place Electrode 7-10

What is a p-Wave
Atrial Depolarization
What is the QRS Complex
Ventricular Depolarization
What is a T-wave
Ventricular Repolarization
What is the PR interval
Time from Atrial to ventricular Depolarization
What is a sinus Rhythm and is it safe
Positive P wave, Followed by QRS and T, (Safe)
What is Sinus Rhythm Tachycardia and is it safe?
Accelerated sinus rhythm, >100bpm, (Safe)
What is Sinus Bradycardia and is it safe?
Normal Sinus Rhythm <60 BPM, (Safe)
What is Atrial Fibrillation and is it safe (in ECGs)?
P waves Highly Irregular, (Not safe, Terminate exercise)
What is Atrial Flutter and is it safe?
Atrial Depolarization is organized, Saw Toothed in appearance (Not safe)
What is Premature Ventricular Complex and is it safe?
P wave may be hidden, because because Ventricle contracted early (Safe look at r-r)
