Pacemakers Flashcards
What does a capture mean
Pacemaker has depolarized the chambers
What does a pacing spike show
Pacemaker has discharged and electrical impulse
What type of a pacemaker is not programmed to sense electrical activity/set at a constant rate
Asynchronous/fixed
Which type of pacemaker is programmed to sense intrinsic electrical activity
Synchronous/demand
Which type of pacemaker is external
Transcutaneous
Which type of pacemaker is delivered through the chest muscle to the ❤️ via 2 electrode patches
Transcutaneous
Which type of pacemaker requires large amounts of electricity ➡️ painful
Transcutaneous
Which type of pacemaker is only used in emergent resuscitation of a client who does not have pacing wires inserted
Transcutaneous
Which type of pacemaker is attached directly to the ❤️ during surgery
Epicardial
Which type of pacemaker is transcend us
Endocardium
Which type of pacemaker is threaded through a large central vein or R vent/atrial wall
Endocardial
Which type of pacemaker is indicated for chronic or recurrent dysrhythmias
Permanent
Which type of pacemaker can be programmed to pace the atria and/or ventricles
Permanent
What does the 1st letter of the pacemaker code stand for
Chamber paced
What does the 2nd letter of the pacemaker code stand for
Chamber sensed
What does the 3rd letter of the pacemaker code stand for
Mode of response
What does the 4th letter of the pacemaker code stand for
Programmable functions
What does the 5th letter of the pacemaker code stand for
Tachydysrhythmic functions
What are 5 complications of pacemaker insertion
Infection Pneumothorax Arrhythmias Hematoma Hemothorax
Pacemaker complication:
Pacemaker initiates a stimulus but depolarization of the ❤️ does not occur
Failure to capture
Pacemaker complication:
Caused by dislodgement, MI, antidysrhythmic meds,
Failure to capture
Pacemaker complication:
Pacemaker fails to sense the ❤️s intrinsic electrical activity ➡️ unnecessary stimulus
Failure to sense
How is failure to sense treated
⬇️ amplitude recognition
If a pacemaker discharges during a T wave what can result
Life-threatening tachydysrhythmia
Pacemaker complication:
Caused by a broken wire or dead battery
Failure to pace
Pacemaker complication:
Pacemaker senses excessive electrical activity
Oversensing
