This paper presents a simulation study on the identifiability of multiple reentrant circuits on the basis of the vectorcardiogram. The methods involved include an advanced tracking of the basic frequencies of the dominant rotors and a supporting identification based on the observed loops of their vectorcardiogram. The vector cardiogram was derived from body surface potentials spatially sampled by different lead systems. The results indicate that up to three independent circuits can be identified reliably.
