CARDIAC ARRHYTHMIAS ACTUAL EXAM 2025 | 50 QUESTIONS WITH
VERIFIED ACCURATE SOLUTIONS
1. In the rhythm called "Atrial Flutter" the atrial rate is usually in the range of
_ __ bpm.
200-240
60-100
250-350
100-130
2. What characteristics are associated with Atrial Flutter?
Recurring, regular, sawtooth shaped flutter waves
Atrial rate of 200-350 beats/minute
Atrial and ventricular rhythm is
regular PR interval is not
measurable
QRS is normal
3. If a patient presents with an EKG showing a regular rhythm, a heart
rate of 185 bpm, prolonged QRS duration, and no visible P waves,
what immediate action should be taken to address the potential risks
associated with this condition?
Monitor the patient for 24 hours.
Administer antiarrhythmic medication.
, Prepare for possible cardioversion.
Increase fluid intake.
4. A patient comes in and tells you that her heart feels like it is beating
out of her chest. To check things out, you take an ECG, which shows
this image: You diagnose her as having atrial fibrillation, and to arrive
at this diagnosis, you note that the ECG does not have any discernible
P-Waves. This tells
, you that which group of cells is being overridden to increase the
heart rate?
AV Node
Bundle
Branches
Internodal fibers
Purkinje
fibers
SA Node
5. Explain why immediate defibrillation is critical in cases of
Ventricular Fibrillation.
It restores normal electrical activity, allowing the heart to pump
blood effectively.
It increases the heart rate to improve blood flow to the
brain. It prevents the heart from entering a state of
asystole.
, It allows for the administration of medications to stabilize heart
function.
6. What is the correct sequence of the electrical conduction pathway in
the heart starting from the SA Node?
SA Node, AV Node, His Bundle, Right bundle branch, Left
bundle branch, Purkinje fibers
AV Node, SA Node, His Bundle, Purkinje fibers, Right
bundle branch, Left bundle branch
