The smaller of the two chambers
What is the ATRIUM
This starts the cardiac cycle
What is the SINOATRIAL Node
Bipolar leads use this many electrodes for images
What is 2
This is the first wave of the cardiac cycle
What is the P wave
The atria is unable to depolarize
What is Atrial Flutter
The valve between the left atrium and the left ventricle
What is the BICUSPID/MITRAL Valve
A small delay happens between the SINOATRIAL NODE and this
What is the ATRIOVENTRICULAR NODE
Chest leads V1-V6 are known by this name
What is PRECORIDAL Leads
Its complex, but this section of the cardiac cycle show contraction of the ventricles
What is QRS Complex
What is Contraction/Depolarization
What is the AORTIC valve
Conduction from the bundle branches comes from this
What is the BUNDLE OF HIS
This lead is considered the GROUND
What is RL (GREEN)
Ventricular repolarization is shown by this
What is T wave
Patient position for a 12 lead ECG
What is a semi fowlers
The 4 valves of the heart
What is the BICUSPID(MITRAL) TRICUSPID PULMONARY and AORTIC
Conduction from the SA to AV NODE causes this
What is Atrial Depolarization
Residing in the 5th intercostal space, Lead V4 is located in this anatomical area of the body
The only wave not seen during the cardiac cycle
What is Atrial Repolarization
This lead is what we interpret most
What is LII/V5
This is the biggest of the 4 chambers
What is the LEFT VENTRICLE
During this stage, the ventricles begin to fill with blood
VENTRICULAR REPOLARIZATION
Electrocardiography was developed and is still taught by his triangular theory
Who is EINTHOVEN
Inverted waves are due to this
Cardiac activity is moving AWAY from electrode
5 small boxes equal one 1 big box and 5 big boxes equal
What is 1 second
