We describe the case of a 78-year-old patient who received a dual-chamber pacemaker implant ten years ago due to sick sinus syndrome, first degree heart block and right bundle branch block and now presents with an incessant wide QRS tachycardia with alternating morphology between deflagration and inhibition of the pacemaker’s ventricular channel.
