Initial assessment of the ABCs (airway, breathing, and circulation) is critical in the management of the patient with<unk><unk>  tachycardia.  Patients who are hemodynamically unstable should undergo immediate cardioversion.  Hemodynamic stability does not reliably differentiate VT from SVT.  Patients with ventricular tachycardia can often be hemodynamically stable, and stable vital signs do not rule out ventricular tachycardia.  This is often a major mistake on the part of clinicians and can lead to inappropriate treatment of VT as SVT with poor outcomes.
