ADVENT HEALTH EKG (ACTUAL2024-2025)QUESTIONS WITH ANSWERS
ventricular tachycardia - <,Answers>>>3 or more PVC's in a
row
• Rate: Ventricular is greater than 100;
Atrial rate is not discernable [N/A]
• Rhythm: Ventricular is usually regular;
Atrial is not discernable [N/A]
• P waves: if there are P waves, they are buried in the QRS
• PRI: N/A
• QRS: ≥ 0.12
ventricular fibrillation - <,Answers>>>Multiple foci in the
ventricle become irritated and generate uncoordinated, chaotic
impulses that cause the heart to fibrillate instead of contract
• Atrial and Ventricular rate & rhythm, PRI, QRS all non-
discernable [N/A]
-LETHAL!
Asystole - <,Answers>>>There is no electrical pacemaker to
initiate electrical flow— All electrical activity lost.
• Atrial and Ventricular rate, rhythm, PRI & QRS: N/A
-LETHAL!
, ADVENT HEALTH EKG (ACTUAL2024-
2025)QUESTIONS WITH ANSWERS
Pulseless Electrical Activity (PEA) - <,Answers>>>There is a
rhythm on the monitor, but the patient has no pulse.
• Depolarization is not the same as contraction. Depolarization
is an electrical event expected to result
in contraction (a mechanical event).
• Electrical activity on the monitor, but no palpable pulse =
PEA.
• It can be ANY rhythm!!!
• PEA is a clinical situation, not a specific dysrhythmia.
-LETHAL!
Bundle Branch Block - <,Answers>>>Impulse travels from
SA node to AV node, blocked at bundle branch level,
bypasses
nonworking branch spreads to opposite ventricle via Purkinje
fibers causing ventricle
depolarization
• Contraction takes longer leading to wide QRS
• Underlying rhythm must first be identified!
• QRS: Wide; ≥ 0.12
-Treatment: atropine or pacemaker
1st degree Heart Block (1st Degree block, 1st degree HB) -
<,Answers>>>The electrical impulse begins in the SA node
, ADVENT HEALTH EKG (ACTUAL2024-
2025)QUESTIONS WITH ANSWERS
then is The electrical impulse begins in the SA node then is
delayed in the AV node longer than normal
due to a partial block and lastly conducts normally through the
ventricles.
• Underlying rhythm must first be identified!
• Rhythm: Atrial and Ventricular regular
• Rate: Atrial and Ventricular rates the same
• PRI: Prolonged >0.20, but constant
• QRS: Usually within normal limits
2nd Degree Heart Block Type I (2
and degree Type I) - <,Answers>>>• Impulse starts in the SA
node, travels to AV node, gets delayed at AV node.
Progressive delay (partial block,
longer PRI), Impulse does not get release (complete block,
dropped QRS)
• Rhythm: Atrial is regular; Ventricular is irregular
• Rate: Atrial rate is greater than ventricular rate
• P waves: Normal in size and shape, but not all followed by
QRS
• PRI: Lengthens
• QRS: Usually within normal limits, but is periodically
dropped
