During a supraventricular tachycardia procedure, when the ablation catheter was connected to the ampere it did not register and the case was cancelled.Connecting the ablation connector did not resolve the issue and the generator displayed a message stating: "no catheter connected".The connector and diathermy patch were replaced, without resolution.Signals were noted and the catheter was displayed on ensite x, however there was no ablation and the procedure was cancelled with no consequences to the patient.
