    - to do prior
    • - 25-28 seconds
    • - When a vessel wall or tissue is injured thrombus tries to form to stop the bleeding; this activates the clotting cascade of which there are two pathways;Intrinsic which is the PTTand aPTT (partial thrombo plastin time)Extrinsic pathway is the PT or Prothrombin time
    • - PTT and aPTT used to assess effects of heparin therapy Therapeutic heparin therapy want the level at 1.5‐2.5 times the patients baseline value; PT is used to assess effects of Coumadin (warfin) INR is a standardized method of reporting PTs; INR 2.0‐3.0 times normal forDVT, PE, Atrial FibINR 2.5‐3.5 times with mechanical prosthetic heart valves

    - comments
    - prior to procedure
    • - Pharmacological stress test is done for the deconditioned, physically disabled who cannot achieve their target heart rate Use 3 vasodilating agents: persantine and adenosine,now primarily use adenosine because of the short half life of the medication (10 seconds)(effects last about 15-30 minutes side effect of chest discomfort, dizziness,headache, flushing, nausea)
    • - If pharmacological test:Not eat drink 4 hours prior No Stimulants (coffee, tea, chocolate…_If taking aminophylin or theophyline should stop taking medication 24-48 hours prior instruct what to expect and side effects will disappear early Instruct what to report to cardiologist or nurse Can take up to 3 hours
