Absolute contraindications to adenosine
Absolute contraindications include irregular or polymorphic rhythms and ventricular pre-excitation.
For conversion of paroxysmal SVT, ______ are an effective alternative to adenosine.
non-dihydropyridine calcium channel blockers (verapamil and diltiazem)
*If given to patients with VT, calcium channel blockers can cause hemodynamic collapse, whereas adenosine is safe
Diltiazem Dose
Dosed at 0.25 mg/kg IV over 2 min
A subsequent dose of 0.35 mg/kg IV is administered if no response is seen and no significant drug-induced adverse event occurs.
If stable paroxysmal SVT does not respond to adenosine or a calcium channel blocker, ______________ is indicated.
electrical cardioversion with appropriate sedation
If the QRS complex is ________________ AV nodal blockers should be avoided.
widened (or of changing morphology) or the rhythm is irregular
______ on ECG is diagnostic of Wolff-Parkinson-White syndrome.

Diagnosis of DIC involves a combination of laboratory tests and clinical evaluation. Laboratory findings suggestive of DIC include
low platelets
elevated D-dimer
decreased fibrinogen
prolongation of clotting times ie PT

The traditional pentad of fever, microangiopathic hemolytic anemia, thrombocytopenia, renal dysfunction and neurologic deficits reflects?
TTP
HUS shares some clinical features with TTP. Both manifest as microangiopathic hemolytic anemia and thrombocytopenia; however, HUS emphasizes renal injury while TTP shows minimal renal injury, instead causing ___________________
neurologic dysfunction in up to 50% of affected patients.
