Lead Placement
This lead is known as the ground lead
What is RL (right leg)?
This is the most common arrhythmia, also know as an irregularly irregular rhythm
What is afib (atrial fibrillation)?
This node (also known as the pacemaker of the heart) is located in wall of right atrium and generates impulse that flows to AV node
What is SA node?
Each large square on an EKG strip is made up of this number of small 1mm squares
What is five?
The proper name for a blood pressure cuff
What is a sphygmomanometer (blood pressure cuff)?
This lead is placed in the 4th intercostal space (ICL) to the right of the sternum
What is lead V1?
This common artifact is due to detached/loose cable or wire, crossed wires
What is flatline?
This term refers to relaxation of the cardiac muscles
What is repolarization?
This wave on an EKG represents atrial contraction (or depolarization)
What is the p wave?
This number is obtained from subtracting systolic blood pressure from the diastolic blood pressure
What is the pulse pressure?
This lead is placed at the 5th intercostal space, mid-clavicular line
What is V4 lead?
The most common type of ventricular arrhythmia
What is ventricular tachycardia?
The chamber of the heart releases oxygenated blood to the body
What is the left ventricle?
What is the QRS complex?
The most common cause of hypertension
What is essential hypertension (no identifiable causes)?
This lead is placed at the same level as V5 lead, left mid-axillary line
What is V6?
This type of second degree AV block is where the PR intervals get progressively longer and then QRS complex drops
What is Mobitz Type 1 (or Wenckebach) 2nd degree AV Block?
These fibers make the ventricles contract
What are the Purkinje fibers?
This interval represents the delay of AV node to allow filling of ventricles
What is the PR interval?
This stage of hypertension is when the systolic blood pressure is 140-180 and/or the systolic blood pressure is 90-120
What is Stage 2 Hypertension?
These 3 leads are know as the bipolar leads
What are leads I, II and III?
This type of second degree AV block is where there are constant PR intervals before blocks occur
What is Type 2 Mobitz second degree AV block?
This node located between atria sends an impulse to the Bundle of His to make the ventricles contract
What is the AV node?
The 5 steps of EKG interpretation
What is 1. Heart rate, 2. regularity, 3. p waves, 4. QRS complex, 5. P-R interval
Systolic blood pressure above 180 and/or diastolic blood pressure above 120 is also know as
Hypertensive Crisis
