Rhythm Interpretation

Question 1

What is VF

Answer 1

Shockable rhythm. Chaotic ventricular activity, no cardiac output. Disorganised ECG - impulses irregular around 300-500 per minute

Ineffective quivering of the myocardium

Initial treatment with defib, quick deterioration as heart becomes anoxic and becomes asystole

Question 2

Management of VF

Answer 2

Defibrillation (shockable pathway)

Question 3

What is pulseless VT

Answer 3

3 or more consecutive PVC occurring rapidly.
Indicates myocardial irritability
QRD complex - wide and bizarre
Rate usually 150-220
Rates >180 more likely to become pulseless - no time for ventricular filling

Question 4

Management of VT

Answer 4

Left untreated, VT deteriorates to VF
Defibrillation following shockable pathway
