Localisation of the origin of a ventricular tachycardia
The localisation of the origin (or exit site) of a ventricular tachycardia can be helpful in understanding the cause of the VT and is very helpful when planning an ablation procedure to treat a ventricular tachycardia.
Using this approach and the algorithm on the right [2] the exit site can be estimated with reasonable accuracy (PPV around 70%).
