(FIT)-Module 5 Workshop 8: Device Cases-Poole Case 4 Question

Video Transcription

Video Summary

A 78-year-old woman with a dual-chamber pacemaker is in the ICU for sepsis, with concerns her pacemaker isn't functioning. Despite having a heart rate of 70 bpm, she's hypotensive and on dopamine. Her pacemaker is programmed DDD with specific settings: a lower rate of 60 bpm, an upper tracking rate of 120 bpm, sensed AV delay of 200 ms, paced AV delay of 180 ms, and PVARP of 240 ms. After reviewing ECG tracings over three days, potential explanations include the pacemaker malfunctioning, needing PVARP extension, a dislodged ATL lead, or that the pacemaker is working as intended.
