rhythmias
2. no matter the assess the patient first!
rhythm always *tolerance of rhythm determines interventions
______ *assess for decreased CO
3. ventricular -p wave is absent
rhythms -QRS is wide and bizarre
-rate: 20-40 bpm
4. premature ven- typically do not perfuse (CO can decrease if consistent)

tion (PVC) *QRS >0.12 and opposite direction T wave
**high risk for developing VT (TREAT CAUSE
5. Uni-focal PVC have similar shape and size
6. Multifocal PVCs varied shapes and forms
7. Occasional PVC 1-4 per minute
8. frequent PVC more than 5-7 per minute
*could be due to electrolyte imbalances or too much caffeine
9. Bigeminy PVC every other beat is a PVC
10. trigeminy PVC every third beat is a PVC
