    Given his age and the monitor “found” P-waves, I was wondering what folks used for “age-predicted maximal sinus rate” to evaluate for inclusion of SVT. 220-age gives 135 for this gentleman, a few papers suggest 208-(0.7 x age) which gives 148! Quite the range.

    Granted I’m not suggested the rate be treated as SVT 🙂

    Thought I would post here because there is so much dialogue on the other link.
    Just a question…chris could probably answer.

    Im going with pulsatile VT – maybe some rate induced ischaemic changes primarily STE inferiorly. Treat VT first obviously.

    The question is if he has a pacemaker insitu and no spike seen does this mean the pacemaker has failed and this is the underlying rythm?

    I need to review pacemakers etc…again 🙁
