The battery was replaced at 2155.
The next morning, the battery had no charge and the pacemaker stopped functioning at 0730.
The night nurse stated that there was no low battery warning indicator when she checked on the patient at midnight and 0400 and at bedside report at 0700.
The patient was pacemaker dependent and went into asystole for about 30 seconds until the patient was connected to the backup pacemaker from the crash cart.
====================== health professional's impression======================per biomed dept: testing in biomed showed no problem, but there is a recall for certain medtronic dual chamber pacemakers (recall # 2011-011, and # 2011-050).
The described symptom matches the recall alert, but this pacemaker is not on the medtronic affected list.
This is a reportable event.
A fresh battery should last for 7 to 9 days, and give a low battery warning indicator 12 hours before the device stops working.
