increase sensitivity of pacemakers by lowering mV

---

• pacemaker will see based on how high the “brick-wall” is
• 0.5: will see QRS but will also see T wave
• increase sensitivity by lowering number on pacemaker
• increase sensitivity leads to pacemaker sense more noise and less pacing
• decrease sensitivity by increasing the mVolts
• decrease sensitivity leads to pacemaker sense less and more pacing
• atrium usually need 0.5 mV sensing
• ventricles need 2.0 mV sensing

• increase sensitivity
• pacemaker capturing but not sensing patient’s own rhythm¹
