Anomalous “VVI” Pacing of a Dual Chamber Pacemaker When Programmed in DDI(R) Mode

We describe the case of a dual chamber rate responsive pacemaker (Relay, model 294‐03, Intermedics, Angleton, TX, USA) implanted in a 68‐year‐old male for sick sinus syndrome, which was not working properly when programmed in the DDIR mode, thus determining occasionally a sort of “VVI” pacing.

Description
Summary:We describe the case of a dual chamber rate responsive pacemaker (Relay, model 294‐03, Intermedics, Angleton, TX, USA) implanted in a 68‐year‐old male for sick sinus syndrome, which was not working properly when programmed in the DDIR mode, thus determining occasionally a sort of “VVI” pacing. However, the pacemaker performed well when programmed in the DDDR mode. We discovered that this was not a malfunction of a single device but rather a general behavior of this family of Intermedics dual chamber pacemakers (also not rate responsive), caused by a software problem.
