ECG Certification Test Flashcards
Why a 12-Lead EKG is used?
It provides a tracing of the electrical activity in the patient’s heart
Page 4
Know the difference between a 12-Lead EKG, Telemetry Monitoring, a Treadmill Stress Test, and a Holter Monitor
12-Lead EKG:
Telemetry Monitoring:
Treadmill Stress Test:
Holter Monitor:
Page 4-5
Know what an AED (Automatic External Defibrillator) is used for.

Know the normal ranges for adult vitals
- pulse
- respirations
- blood pressure
pulse:
respirations:
blood pressure:
Page 19
Know the parts of the conduction system
SA Node
AV Node
Bundle of His
Bundle Branches
Purkinje Fibers
Page 45
Know polarization, depolarization, repolarization
polarization:
depolarization:
repolarization:
Pages 46-47
Know what ischemia means
Page 48
Know the normal depolarization time for the QRS Complex
0.06-0.12 seconds
Page 48
Know the normal length of time for the PR interval
0.12-0.20 seconds
Page 49
Know the colors of the lead wires.
Page 60
Know which leg is used as the ground leg and the color of the lead wire
Right leg, green wire
Page 60
Know what the Einthoven’s Triangle is
It is formed by only three limb electrodes
Page 62
Know the chest lead placements
Page 61, Tabe 3-2
Know where the midclavicular, anterior axillary line, and mid-axillary lines are and what chest leads go in those areas
Pages 96-98, Tabe 4-4
Know what the augmented leads are
Lead aVR is usually a negative deflection
Pages 62-63
Know what speed control and that you may have to increase the speed to 50mm/sec when a patient has a rapid heart rate
Page 70
Know what gain is - also known as sensitivity
Gain control regulates the output or height of the EKG waveform
Page 71
Know that EKG graph paper consists of horizontal and vertical lines
horizontal represents time in seconds
vertical represents voltage
Page 77
Know the difference between Somatic tremor, Wandering Baseline, Alternating Current (AC) Interference, and Interrupted Baseline
A LOT OF QUESTIONS ABOUT SOMATIC TREMOR
Pages 102-106
Know that with infants and children the speed of the paper might need to be adjusted to 50mm/sec because they have very fast heart rates.
Adjusting the speed will allow the physician to view each of the deflections on the EKG tracing.

Know where to place electrodes with patients that might be pregnant, have had a mastectomy, or is an amputee.
Pages 111-113
Know what to do if a patient has a seizure.
Pages 115-116
Know what a myocardial infarction means.
Heart attack
Page 167
Know what dextrocardia is.
When the heart is on the opposite - right side - of the chest
