Sustained ventricular tachycardias

Pulseless ventricular tachycardia (VT)

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

VT with a cardiac output

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

• Haemodynamically unstable/unwell: patient with weak pulse and hypotension, signs of diminished cerebral perfusion (light-headedness, dizziness, diminished responsiveness, or unconsciousness) or diminished coronary perfusion (chest discomfort, dyspnoea).
