Abstract :
The authors are using basket electrodes to validate electrical-thermal computer models of RF catheter ablation for the cure of tachycardias. They have measured electrical characteristics of the basket electrode and shown that accuracy degrades above 100 kHz. They present some preliminary measurements and suggest considerations for the validation of the model for RF catheter ablation
