Ekg Interpretation

1. What EKG finding is consistent with Wenckebach?

Complete heart block

EKG #
Rate:
Rhythm:
P waves:
PR Interval:

QRS:
Interpretation:2
33 beats/minute
Irregular
Present; the 1st, 2nd, and 4th P waves are followed by QRS complexes
.22 to .36 sec. The PR intervals increase until the QRS complex
fails to follow the P wave
0.10 sec
Sinus rhythm with second degree, type I AV block (Wenckebach)

Atrial fibrillation with rapid ventricular response

Ventricular tachycardia with 1:1 conduction

The correct answer describes the specific EKG findings associated with Wenckebach, such as irregular rhythm with increasing PR intervals until a QRS complex is dropped. The incorrect answers are not characteristic of the Wenckebach pattern.

Explanation

The correct answer describes the specific EKG findings associated with Wenckebach, such as irregular rhythm with increasing PR intervals until a QRS complex is dropped. The incorrect answers are not characteristic of the Wenckebach pattern.

2. What is the interpretation for sinus bradycardia with sinus dysrhythmia?

EKG #
Rate:
Rhythm:
P waves:
PR Interval:
QRS:
Interpretation:3
41 beats/minute
Irregular
Present; precede each QRS complex
0.16 sec
0.08 sec
Sinus bradycardia with sinus arrhythmia

Ventricular tachycardia with supraventricular premature beats.

Sinus tachycardia with atrial fibrillation.

Atrial flutter with heart block.

Sinus bradycardia with sinus dysrhythmia is characterized by an irregular rhythm with a slow heart rate, where P waves are present and precede each QRS complex. This is different from the other incorrect options provided.

Explanation

Sinus bradycardia with sinus dysrhythmia is characterized by an irregular rhythm with a slow heart rate, where P waves are present and precede each QRS complex. This is different from the other incorrect options provided.

3. What is the EKG interpretation for a patient with Atrial Fibrillation?

Atrial flutter

Ventricular tachycardia

EKG #
Rate:
Rhythm:
P waves:
PR Interval:
QRS:
Interpretation:1
126 beats/minute
Irregular
None; fine atrial fibrillation waves are present
None
0.10 sec
Atrial fibrillation

Sinus tachycardia

Atrial Fibrillation is characterized by an irregular heart rhythm, absence of P waves, and fine atrial fibrillation waves on EKG. Ventricular tachycardia, Sinus tachycardia, and Atrial flutter have different EKG characteristics and are not indicative of Atrial Fibrillation.

Explanation

Atrial Fibrillation is characterized by an irregular heart rhythm, absence of P waves, and fine atrial fibrillation waves on EKG. Ventricular tachycardia, Sinus tachycardia, and Atrial flutter have different EKG characteristics and are not indicative of Atrial Fibrillation.

4. What arrhythmia is characterized by an irregular rhythm with P waves preceding each QRS complex at a rate of 182 beats/minute?

Sinus tachycardia

EKG #
Rate:
Rhythm:
P waves:
PR Interval:
QRS:
Interpretation:4
182 beats/minute
Irregular
Present; precede each QRS complex
0.08 sec
0.09 sec
Atrial tachycardia

Ventricular tachycardia

Atrial flutter

Atrial tachycardia is characterized by an irregular rhythm with P waves preceding each QRS complex, as seen in the provided EKG interpretation. Sinus tachycardia would have regular P waves, while atrial flutter typically presents with sawtooth-shaped P waves and ventricular tachycardia originates in the ventricles.
