HEART RHYTHMS (EKG Questions with Correct Solutions
Question:
1. normal sinus rhythm (NSR)
Answer:
regular rhythm of the heart cycle stimulated by the SA node (average rate of 60-100
beats/minute)
Question:
2. Sinus Bradycardia
Answer:
<60 bpm
Question:
3. Sinus Tachycardia
Answer:
>100 bpm
Question:
4. Premature Atrial Contraction (PAC)
Answer:
irregular heart rhythm characterized by atrial contractions occurring before the expected
time
, Question:
5. Supraventricular Tachycardia (SVT)
Answer:
an abnormal heart rhythm arising from abnormal electrical activity in the heart; originates at
or above the AV node
Question:
6. Sinus Arrest
Answer:
- SA node doesn't fire
- notice absence of P-wave for a complete cycle (a missed cycle)
Question:
7. Sinus Arrhythmia
Answer:
A sinus rhythm in which the rate varies with respiration, causing an irregular rhythm.
Question:
8. atrial fibrillation
Answer:
occurs when the normal rhythmic contractions of the atria are replaced by rapid irregular
twitching of the muscular heart wall
Question:
9. Preventricular Contraction (PVC)
Answer:
Abnormal beat generated from the ventricles. Characterized by a wide and bizarrely shaped
QRS.
