In this case unless I missed something you have only nurses expressing concern, but a patient with no symptoms. While it was advisable to continue to monitor patient for changes enroute to hospital all treatment should be based on patient not on that funny little box that makes up down lines. Was fiznat wrong to follow cardiac protocol? No, a supposed higher level of care said it was a cardiac call. But their statement may have clouded thinking processes. The question I have for fiznat is would you have treated same way if you had been only person with medical education to evaluate this patient, no input from others? If yes then you did what you thought was best for patient.
Thanks for interesting case. And other poster thanks for link with info on this abnormality.
