Large, wide QRS complexes and no identifiable P waves indicate which abnormal rhythm?
Ventricular Tachycardia. (VTach)
Name the colors of the precordial leads in order from right to left.

If a patient has a hairy chest, what should the MA do to avoid a wandering baseline?
Clip or trim the hair
ICD-10 codes are also called ______ codes.
Diagnosis
Which chamber of the heart pumps oxygenated blood to the body?
Left Ventricle
Which part of the cardiac cycle does the P wave represent?
Atrial Contraction (depolarization)
This rhythm has no waves. It is a straight line.
Asystole
Where would you place the limb lead for a person who has had a left leg amputated?
left abdomen or left thigh
What causes somatic tremor interference?
Patient movement
What is the term for the amount the patient pays at the time of their appointment?
Copay
Which valve is located between the right atrium and the right ventricle?
Tricuspid Valve
What does the T wave represent in an EKG tracing?
Ventricular Repolarization (Relaxation)
Which abnormal heart rhythm occurs when the atria are quivering? Patients with this rhythm are at a greater risk for a stroke.
A-fib (Atrial Fibrillation)
Which lead is placed in the 5th intercostal space, midaxillary line?
V6
This type of artifact produces uniform, sharp spikes due to electrical equipment nearby.
AC interference
How many digits is a CPT Code?
5
The Sinoatrial Node (SA Node) is often called this.
Pacemaker
Which part of the EKG strip represents ventricular contraction?
QRS Complex
This type of early heartbeat originates in the ventricles and is often described as a “skipped beat” or “extra beat.”
PVC (Premature ventricular contraction)
How many seconds is one BIG square on EKG paper?
0.20 seconds
Which type of artifact is caused by poor electrode connection?
Wandering baseline
Which part of Medicare covers ambulatory visits and durable medical equipment?
Part B
Right
Depolarization means:
Which abnormal rhythm occurs when the atria are contracting at a faster rate than the ventricles?
Atrial Flutter
Which electrode acts as the grounding lead in a 12-lead EKG?
Right Leg
The MA notices a break in the EKG tracing. What should she look for?
Broken or disconnected lead wire or electrode
Which claim form is typically used to process insurance claims?
CMS 1500
What do the Purkinje Fibers signal the heart to do?
Tells the ventricles to contract
How much time does one large box on the EKG Strip represent?
0.2 seconds
In this abnormal rhythm the ventricles are quivering.
Ventricular fibrillation
Which leads are known as the "Precordial Leads"?
V1-V6 (Chest Leads)
To remove oils, lotions, etc and help the electrodes adhere to the skin
This type of scheduling puts 3 patients at the top of the hour. They are seen in the order that they arrive.
Wave Scheduling
Blood returns to the heart after receiving oxygen via this blood vessel.
Pulmonary Vein
Explain how to calculate the heart rate from an EKG strip.
Count the number of R waves in 6 sec., multiply by 10. OR use the 1500 method: # of small boxes between 2 R waves, divide 1500 by that #.
