QUESTIONS AND ANSWERS
, BASIC DYSRHYTHMIA-RELIAS EXAM |
QUESTIONS AND ANSWERS
1. normal sinus rhythm: heart rhythm originating in the sinoatrial
node with a rate in patients at rest of 60 to 100 beats per minute
2. Sinus Arrhythmia: Appearance is ALMOST
NORMAL: Respiratory - Circulatory interaction
Rate INCREASES with INSPIRATION (IN=IN)
3. Sinus Bradycardia:
<60 normal sinus rhythm
4. Sinus Tachycardia: >100
(100- 150) normal sinus
rhythm
5. Premature Atrial Contraction (PAC): Heart Rate: Depends
on underlying rhythm
Regularity: Interrupts the regularity of underlying rhythm
P-Wave: can be flattened, notched, or unusual. May be hidden within
the T wave PRI: measures between .12-.20 seconds and can be
prolonged; can be
different from other complexes
QRS: <.12 seconds
6. Sinus Arrest/Pause: - SA node doesn't fire
- notice absence of P-wave for a complete cycle (a
missed cycle) length of pause ` multiple of normal
rate (block)
