One of the nurses on my unit had a pt (due to be discharged) but had a short run of SVT. We called the cardiologist to update. At the time the HR was in the 70s. He ordered dig 0.25mg IV X 3 doses Q4hrs apart.
After the first dose, the HR dropped to and stayed in the low 50s occasionally dropping to the hi 40s. No more dysrhythmias noted. She came to me and told me that she wasn't going to give the second dose. I agreed but told her to call the doc just to update.
He became very irritated (new doc to us) and kept insisting that she give the doses as prescribed. She even ask him what if the HR drops to the 30s by the time the last dose is due? What then? He told her I SAID TO GIVE ALL THE DOSES OF DIG.
I wish I had been the one to call him. I would have loved to tell him, "No sir, I will not give that dose. The HR is too low. I am calling you to update you on the patient's condition. Thank you." And hung up (gently...not rudely:D)
We didn't give the doses and HR stayed in 40-50s all night. I was in a meeting when that doctor came to round. It will be interesting to see what kinds of interactions we are going to have in the future with this cardiologist. If crap like this continues, we will have to have a little chat.
