4/15/25, 10:31 AM EKG STUDY MATERIAL FOR ADVENTHEALTH
ADVENT HEALTH EKG Exam Study
Guide with complete solutions |
100% Correct | Latest 2025/2026.
1. SAnode
2. AV node
3 pacemakers of the heart 3. bundle branch
intrinsic rate of SA node 60-100 bpm
intrinsic rate of AV node 40-60 bpm
intrinsic rate of bundle 20-40 bpm
branches
1. normal conduction impulse
originates in the SA Node
2. impulse travels to AV Node
causing atrial
depolarization
(contraction)
electrical pathway through
the heart
3. AV Node slightly delays
impulse then sends
impulse to Bundle of
HIS
4. then travels to Bundle Branches
5. impulse continues down to
the Purkinje Fibers
causing ventricular
depolarization
(contraction)
atrial depolarization (contraction)
P wave
delay of AV node to allow
filling of ventricles
PR interval
,4/15/25, 10:31 AM EKG STUDY MATERIAL FOR ADVENTHEALTH
ventricular depolarization (contraction)
QRS complex
ventricular repolarization (resting phase)
ST interval
ventricular depolarization
and repolarization
QT interval inversely related to the heart rate
normally less than half of
the length of the R-R
interval
ventricular repolarization (resting phase)
T wave
The baseline of the ECG /
absence of electrical
isoelectric line
activity
a wave that exists above the isoelectric line
positive deflection
a wave that exists below the isoelectric line
negative deflection
cardiac cells will not
respond to further
stimulation
absolute refractory period
myocardial cells will not
contract electrical cells
will not conduct
vulnerable period
relative refractory period cardiac cells can be stimulated to contract
