Banner ECG Exam Prep 2026/2027 | Questions & Correct
Answers | Graded A+
1. What is a key characteristic of ventricular tachycardia (monomorphic VT)?
Heart rate 1:1
Presence of P waves
No P waves
Narrow QRS
2. Describe the significance of the R-R interval in the context of sinus rhythm
with sinus arrest.
The R-R interval measures the duration of the P wave.
The R-R interval indicates the heart rate in normal sinus rhythm.
The R-R interval is irrelevant in the diagnosis of arrhythmias.
The R-R interval is significant because it helps to identify the
irregular pause characteristic of sinus arrest.
3. Atrial fibrillation has the following features:
completely irregular rhythm
drop in cardiac output even to 30%
rapid chaotic rhythm of atria due to reentry mechanism
all mentioned above
no P wave and f wave on ECG
4. If a patient presents with a heart rate of 120 bpm and an ECG shows at least 3
different P wave morphologies, what arrhythmia might they be experiencing?
, Sinus tachycardia
Multifocal atrial tachycardia
Ventricular tachycardia
Atrial fibrillation
5. If a patient presents with a heart rate of 50 beats per minute and an ECG
shows no P waves, what could this indicate?
Ventricular tachycardia
Sinus bradycardia
A junctional escape rhythm
Atrial fibrillation
6. Junctional Escape Rhythm has a HR of?
20-40
60-100
>100
40-60
7. As compared to a normal sinus rhythm, a sinus arrhythmia would result in
which of the following deviations?
Varied P waves throughout an ECG reading
Varied R-R intervals throughout an ECG reading
None of the above
Varied QRS complexes throughout an ECG reading
, 8. In a patient with 3rd degree heart block, what would you expect to observe
on an ECG regarding the relationship between P waves and QRS complexes?
P waves precede every QRS complex consistently.
P waves and QRS complexes are independent of each other.
P waves are absent altogether.
QRS complexes are consistently shorter than P waves.
9. What is the heart rate range for a junctional escape rhythm?
20-40
60-100
100-120
40-60
10. Describe the timing of premature atrial complexes (PACs) in relation to the
normal heartbeat.
PACs occur only during bradycardia.
PACs occur as a premature beat before the next normally expected
beat.
PACs occur simultaneously with the normal heartbeat.
PACs occur after the normal heartbeat.
11. Describe the significance of QRS duration in identifying premature
ventricular complexes (PVCs).
A QRS duration of exactly 0.10 seconds is typical for sinus rhythms.
A QRS duration between 0.08 and 0.12 seconds suggests atrial origin
of the impulse.
