A 52-year-old woman had been treated with implantation of an aortic prosthesis for severe stenosis of a bicuspid aortic valve 37 years previously. During follow-up, she developed progressive, severe prosthetic valve stenosis without ventricular dysfunction that required valve replacement. On the fourth postoperative day, she experienced an episode of loss of contact with her surroundings. Complete atrioventricular block was documented, which persisted in paroxysmal form at 7 days of monitoring; finally, a dual-chamber pacemaker was implanted. Normal functioning of the device was confirmed. On the third day following the procedure, the patient underwent ECG study (Figure 1, ECG during tachycardia; Figure 2, preoperative ECG) to investigate palpitations, her only symptom. What would your diagnosis be?
