Sustained ventricular tachycardias

Pulseless ventricular tachycardia (VT)

• Hemodynamically unstable: patient unconscious with hypotension and undetectable pulse.

VT with a cardiac output

• Hemodynamically stable/well: an alert patient with normal blood pressure.

• Hemodynamically unstable/ill: patient with weak pulse and hypotension, signs of diminished cerebral perfusion (lightheadedness, dizziness, diminished responsiveness, or unconsciousness) or diminished coronary perfusion (chest discomfort, dyspnea).
