false raised trop_t
- 0Mar 2 by ayla2004Im not a cardiac nurse but i had a pt with a false trop-t and i curious about what was going on.
i had a lady tachycardiac 132 with faint radical pulse, rr -23-27
denies any pain
reviewed and in atrial flutter, trop-t raised 39(1 day post clipping of pcom) medics said atrial flutter self limiting no treatment ordered
after handover bloods results potassium was 3.2
not acute coronary syndrome not ami
- 0Mar 2 by nursej22We 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.

- 0Mar 2 by MunoRNThere'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
- 0Mar 2 by ayla2004sorry 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.
