Figure 1 :Catheter ablation of a ‘malignant’ accessory pathway in a patient with aborted sudden cardiac death who was successfully resuscitated. During atrial stimulation the first four QRS complexes are broad and the PQ interval is short due to conduction over the accessory pathway. The last four beats show narrow QRS with normal PQ interval after the accessory pathway was successfully ablated
