    We use Troponin I to detect myocardial ischemia but my understanding is that Troponin T is also used.
    Sorry but I do not understand "clipping of pcom" so I am not sure if this contributes to elevated trop.
    Certainly a rapid heart rate can result in decreased blood flow to coronary muscle. Remember coronary arteries perfuse during diastole, so with a rapid HR there is less oxygenated blood flowing to a muscle that is working harder that normal.

    There's a difference between a false positive troponin and an accurately positive troponin due to non ACS conditions. Troponins can become elevated for a variety of reasons: Elevated cardiac troponin concentration in the absence of an acute coronary syndrome

    sorry i work on a neurosurgical ward, the lady had had a subarachnoid hemorrhage (SAH) from a anersyum on her posteior comunicating aretery so had a craintomy and clipping and I is was wondering if surgery could effect trop=t (anything over 14 is raised)

    as i said she was deemed to be in atrial flutter her dbp stayed around 90ish the entire time.
