1. normal sinus rhythm regular rhythm of the heart cycle stimulated by the SA node (average rate
(NSR) of 60-100 beats/minute)
2. Sinus Bradycardia <60 bpm
3. Sinus Tachycardia >100 bpm
4. Supraventricular an abnormal heart rhythm arising from abnormal electrical activity in the
Tachycardia (SVT) heart; originates at or above the AV node
5. Sinus Arrest - SA node doesn't fire
- notice absence of P-wave for a complete cycle (a missed cycle)
6. Sinus Arrhythmia A sinus rhythm in which the rate varies with respiration, causing an irregular
rhythm.
7. atrial fibrillation occurs when the normal rhythmic contractions of the atria are replaced by
rapid irregular twitching of the muscular heart wall
