Output and Threshold of Pacemakers
- related: cardiac pacemaker
- tags: #literature #cardiology
- output is the amount of mA the machine sends to the wire
- threshold is the minimum mA required to generate depolarization
- in atrium: p wave
- in ventricle: QRS
- in cases where there is sensing but not capturing, output needs to be increased:
- permanent pacemaker and temporary pacemakers differ
- permanent pacemaker can adjust both time delivers (volts) and amplitude (mAmps)
- temporary pacemaker can only adjust amplitude
