Termination of reentry by infra- and supra-threshold pulses

Two different experimental methods to terminate a reentrant activity were studied within the framework of nonlinear electronic circuits, which mimic the discrete nature of cardiac tissue at a microscopic scale. It was shown that trains of low voltage (with infra- and supra-threshold stimulating amplitude) and low frequency (period larger than that of reentry) pulses can be used efficiently to terminate a pinned reentry when applied near to the reentry.
