2024 EKG EXAM 1 WITH CORRECT
ANSWERS

paroxysmal atrial tachycardia - CORRECT ANSWERS-Rate: 160-220
Rhythm: regular
P waves: differ in shape from sinus P's, usually difficult to identify due to high
rate
QRS normal
Onset suddenly, often initiated by a PAC

junctional rhythm - CORRECT ANSWERS-rate: 40-60
rhythm: regular
P waves: inverted before or after QRS or not visible
PR interval: <0.12 second when inverted P is before QRS

Idioventricular Rhythm - CORRECT ANSWERS-Rate: 20-40bpm
Rhythm: regular
P-wave: absent
QRS-complex: wide and bizarre
PR-interval: absent

Asystole - CORRECT ANSWERS-ventricular rate= 0
P waves may be present but no QRS or T waves.


1st degree AV block - CORRECT ANSWERS-Normal sinus rhythm but PR
interval is prolonged
PR interval > .20 seconds - conduction is delayed at AV node

2nd degree AV block Type 1 (Wenckebach) - CORRECT ANSWERS-More P
waves than QRS
PR interval progressively increases in a cycle until P appears w/o QRS
occasional dropped beat
RR intervals not regular

2nd degree AV Block Type 2 - CORRECT ANSWERS-More P waves than QRS
PR interval is *consistent and normal*
multiple dropped beats
QRS regular width

3rd degree AV block (complete heart block) - CORRECT ANSWERS-More P
waves than QRS;

, Sometimes the P waves are hidden within the T wave
No pattern to PR interval, variable
R-R always regular
No atrial impulses are conducted through the AV node. Heart has regular
atrial activity and regular ventricular activity, but the activities are not
coordinated with each other.

Ventricular tachycardia - CORRECT ANSWERS-Tachycardic rhythm
No P waves
*Wide* QRS
May or may not have a pulse (one of the four pulse-less rhythms)

Atrial flutter - CORRECT ANSWERS-Regular rhythm and normal rate usually
P waves are present, but there are *extra ones*
Saw-tooth P waves
QRS normal

Sinus Bradycardia - CORRECT ANSWERS-Bradycardic rate
Regular rhythm
P waves are present for each QRS. No dropped P waves

PVC (Premature Ventricular Contraction) - CORRECT ANSWERS-R-R interval
not regular (irregular rhythm)
Absent P waves
Wide QRS greater than 0.12 seconds; notched and bizarre

atrial fibrillation - CORRECT ANSWERS-Irregularly irregular rhythm
chaotic electrical activity
No obvious P waves
No PR interval
QRS normal


Adenosine - CORRECT ANSWERS-Can treat irregular heartbeats, especially
supraventricular tachycardia. It works to terminate SVTs by binding to the AV
node's A1 receptors

Paced Rhythm - CORRECT ANSWERS-Pacing blip or spike in front of the
chamber paced
Can result in wide QRS

AC interference - CORRECT ANSWERS-uniform spikes on an EKG caused by
electrical interference.

Multifocal PVCs - CORRECT ANSWERS-pattern of premature ventricular
contractions originating from more than one ectopic location
