Pacemakers and Automatic Implantable Cardioverter Defibrillators Exercise Prescription Flashcards
1
Q
what are pacemakers programmed to do
A
pace heart rate
2
Q
do pacemakers have a lower HR limit set?
A
yes
- rarely have an upper limit set
3
Q
demand vs fixed HR pacemakers
A
- demand pacemakers let HR increase as workload increases
- HR does not change with fixed pacemaker, which impacts activity tolerance
4
Q
what do AICDs do?
A
deliver an electric shock if HR exceeds set limit and/or ventricular arrhythmia is detected
- you need to know the limits set
5
Q
what ECG changes are common
A
ST segment changes
6
Q
what should you avoid
A
UE aerobic or strengthening exercises for 4-6 weeks after implant to allow leads to scar down
7
Q
what should you make sure of during exercise
A
that the patients HR remains at least 10 bears below the ICD shock and antitachycardic pacing threshold
