I had been on them for 4 of a 5 day course at the point that this took place. I have read that Darvocet can cause conduction delays, in overdose
, and I had told the ER doctor that I was taking Darvocet and he did not seem concerned. Another question here is, could the Darvocet have been responsible for the above arrhythmia, even in a "theuraputic" dose? My cardio says no, it would only cause such delays in an overdose setting.
