7.5 Managing pacing output energies with Capture
Management
Maintaining adequate safety margins for pacing output energies and optimizing device
longevity are critical to patient care. As the patient’s condition changes, pacing thresholds
may change, requiring pacing outputs to be monitored regularly and modified, if necessary,
to capture the myocardium.
7.5.1 System solution: Capture Management
The Capture Management feature automatically manages pacing thresholds in the right
atrium and right ventricle. It monitors whether pacing pulses capture the myocardium and,
optionally, adjusts their amplitude to changing patient conditions.
7.5.2 Operation of Capture Management
Capture Management is a programmable feature that is available for the right atrium (ACM)
and right ventricle (RVCM). In Capture Management operation, the device prepares for a
pacing threshold search, conducts the pacing threshold search, and determines the pacing
threshold. Over time, the threshold measurements are collected to create threshold trends.
If Capture Management is programmed to Adaptive, the device may automatically adjust
the pacing outputs. If Capture Management is programmed to Monitor, no adjustments
occur.
