I just started working in CICU and I am confused.I had a patient with afib in the 100's then she had frequent 5 beat run of PVc's with heart rate increasing 130's to 140's. It happened frequently so I notified the doctor after I got a lab result called to me. She was asymtomatic patient calm and talkative denies SOB.Her potassium was 2.9. I understand that this can be a cause for irregular heart rhythm. I stayed by her side fearing she would get symptomatic and need a code. She was given a stat dose of lopressor IVP and solucet.What would you call her rhythm afib with RVR or afib with vtach? How many consecutive PVC's would be considered a run?What else could I have done with her symptoms?
