AB -  We write about our concerns regarding the St. Jude Medical (St. Paul, MN, USA) Identity® pacemakers and similar designs (Identity, Affinity, Integrity, ADx, Victory, and Zephyr). It has become evident that there are two clinically significant problems with these devices, which may place pacemaker‐dependent patients at risk. One issue was the extraordinary sensitivity to the presence of electrocautery on or near the device generator. This was dealt with by a communication to physicians from St. Jude Medical on January 29, 2014 explaining that transient (up to 30 seconds) of loss of capture may be seen with a drop in pacing output through the device which cannot be prevented with VOO or DOO mode. The other issue is that, in this family of pacemakers, the elective replacement indicator (ERI) behavior is quite different from other currently available devices. Selzman et al. recently reported this. In some devices, the ERI condition floats with the pulse generator battery voltage such that a device may be at ERI one day, but days later, the battery voltage may drift up and the indicator is no longer present. This may be entirely appropriate for implantable cardioverter defibrillator generators and most pacemakers. In other devices,
