ECG Flashcards
This equipment records a series
of waves and deflections
recording the heart’s
Electrical activity from a
certain “view.
Electrocardiogram
True or False: A 12-lead ECG paints a complete picture of the heart’s electrical activity by recording information through 12 different perspectives
True
These 12 views are collected by
placing electrodes or small, sticky
patches on the: SETA
a. chest (precordial)
b. wrists
c. ankles
d. head
a,b,c
How many leads are used for just cardiac monitoring?
3 smoke over fire
True or False: In a 12-lead ECG, there are 12 leads calculated using 12 electrodes
False. 10 electrodes
How many traces do limb leads produce?
a. 10
b. 6
c. 5
d. 7
b. 6
True or False: N or neutral does produce trace for ECG records
FALSE: N foot does not produce trace but trace interferences and noise
These leads entail the direction of electrical activity
Leads 1 to 3
The leads entail the angle of electrical activity
Augmented RLF leads
