Several ECG algorithms have been developed to differentiate wide QRS-complex tachycardias. Most of them performed very well in the population they were based upon. A recent review tested five commonly used algorithms in a control population and found that each of them only performed reasonably well in differentiating VT from SVT (accuracy 66-77%).<cite>Jastrzekbsi</cite> The five criteria tested were: | Several ECG algorithms have been developed to differentiate wide QRS-complex tachycardias.
