    Guys have you ever seen a patient with a corrected QTc of around 400ms get pushed into long QT with the addition of Zithromax? Or for that matter go onto to have TdP?

    Great episode I learned a lot. Calcium calcium calcium! That was cool!

    I have never seen a patient with a QTc of 400 pushed into long QT via ZMax or develop Tdp. I'd think most drugs that prolong the QTc do so in very small amounts, so I don't worry about this very much.
    I only start worrying about new drugs pushing the QT into dangerous levels when the QTc starts near 500. But 400?? Nothing in medicine is 100%, but this is no worries to me.
