716 medical device reports received by FDA name the brand "Quickflex Xl Lv Lead" (permanent pacemaker electrode); the manufacturer given most often on reports is St Jude Medical Cardiac Rhythm Management Division; received from May 2008 to August 2026. Brand names are as the reporter or manufacturer wrote them, so one product can appear under several spellings.

8 reports arrived in the 12 months to August 2026, close to the 8 of the 12 months before. FDA releases MAUDE data monthly; reports can arrive months after an event, so the newest months grow in later releases. The event types recorded are injury (48.6%), malfunction (40.2%) and death (11%); across all drug eluting permanent left ventricular (lv) pacemaker electrode reports (product code OJX) death is recorded in 3.5% and malfunction in 40.2%. Event type is the reporter's classification of the report, not a verified outcome.

The device problems coded most often are device dislodged or dislocated (19.4%), failure to capture (15.4%) and high capture threshold (11.3%). The patient problems coded most often are death, muscle stimulation and surgical procedure. FDA states that "MDR data alone cannot be used to establish rates of events, evaluate a change in event rates over time or compare event rates between devices. The number of reports cannot be interpreted or used in isolation to reach conclusions about the existence, severity, or frequency of problems associated with devices." It adds that the reporting system "has limitations, including the potential submission of incomplete, inaccurate, untimely, unverified, or biased data."
