Blue
Unwanted, erratic movement of the stylus on paper caused by outside interference
Artifact
Painless test used to assess electrical activity of the heart
Electrocardiogram
The person who interprets the ECG
The medical provider
The heart consist of how many chambers
Four
Should the MA read or interpret the ECG for the patient
No this is outside the MAs scope of practice
Interference caused by electrical devices like a cell phone, tablet, laptop
AC Interference
Adhesive patches that conduct electricity from the body to the ECG machine
Electrodes
Heart rate above 100 beats per minute
Tachycardia
Type of ECG done while pt is exercising such as a walking on a treadmill or riding an exercise bike
Exercise Stress Test
The heart wall has this many layers
Three
The phase when the heart is at rest and the atria fills with blood
Diastole
This type of stress test is implanted under the skin and has a flash drive appearance
Implantable Loop Recorder
This type of stress test uses a radioactive substance and a gamma camera
Nuclear Stress Test
Divides the heart from the left side to the right side
The Septum
Oxygenated blood exit the heart via
The Aorta
Represents atrial depolarization
P wave
Used to monitor heart over a one to two day period while patient goes about their normal activities
Holter Monitor
Heart rate less than 60 beats per minute
Bradycardia
The phase when the heart is contracting
Systole
This type of artifact is from involuntary or voluntary movement such as shivering, talking, chewing gum, etc
Somatic Tremor
This type of ECG is worn over a longer period of time, such as 30 days and the pt will push an activation button when experiencing symptoms
Cardiac Event Recorder
This is how ECG lead wires are typically labeled
Color coded and abbreviated
Artifact is is appearing on leads ll and lll what electrode should you check?
Left leg
