RF heating of a diagnostic multi-polar EP mapping-catheter equipped with resistive leads for ECG signal transmission was investigated by electromagnetic simulations and subsequent measurements. The influence of wire resistance and number of wires in the catheter has been adressed. The simulations were validated by fiberoptic temperature measurements on a prototype catheter employing resistive leads.
