Ekg Interpretation Expected Questions With Verified Answers

EKG INTERPRETATION EXPECTED QUESTIONS WITH
VERIFIED ANSWERS

Question 1.
Accelerated Idioventricular Rhythm

ANSWER
i. Rhythm: Regular
ii. Rate: 50-120 bpm
iii. P Wave: Absent
iv. PR Interval: Not measurable
v. QRS: Wide (>0.10 sec), bizarre looking




Question 2.
Accelerated Junctional Rhythm

ANSWER






,Question 3.
Atrial Fibrilation

ANSWER
Irregularly irregular with no discernible p wave
Rhythm: Irregular
Rate: Very fast (> 350 bpm) for Atrial, but ventricular rate may be slow, normal or fast
P Wave: Absent - erratic waves are present
PR Interval: Absent
QRS: Normal but may be widened if there are conduction delays
Cause: continuous rapid-firing of multiple atrial automaticity foci. No complete depolarization
of atria.




Question 4.
Atrial Flutter

ANSWER
i. Rhythm: Regular or irregular
ii. Rate: Fast (250-350 bpm) for Atrial, but ventricular rate is often slower
iii. P Wave: Not observable, but saw-toothed flutter waves are present
iv. PR Interval: Not measureable
v. QRS: Normal (0.06-0.10 sec)






, Question 5.
Ventricular Flutter

ANSWER
Rate: 250-350bpm
Smooth sine waves of similar amplitude.
So rapid that ventricles hardly have time to fill.




Question 6.
Bundle Branch Block

ANSWER
i. Rhythm: Regular
ii. Rate: The underlying rate
iii. P Wave: Normal
iv. PR Interval: Normal (0.12-0.20 sec)
v. QRS: Wide (>0.12 sec)
