Cards In This Set

Front Back
A vertical line on the ECG that indicates the pacemaker has discharged
Pacemaker spike
A pacemaker malfunction that occurs when the artificial pacemaker fails to recognize spontaneous myocardial depolarization
Undersensing
A pacemaker malfunction that occurs when the artificial pacemaker stimulus is unable to depolarize the myocardium
Failure to capture
The period between two consecutive paced events in the same cardiac chamber
Paced interval
This type of pacemaker stimulates the atrium and ventricle
Dual-chamber
In dual-chamber pacing, the length of time between an atrial sensed or atrial paced event and the delivery of a ventricular pacing stimulus; an artificial or electronic PR interval
AV interval
This type of pacemaker continuously discharges at a preset rate regardless of the patient's intrinsic activity
Fixed-rate
Ability of a pacemaker to increase the pacing rate in response to physical activity or metabolic demand
Rate modulation
A pacemaker malfunction that results from inappropriate sensing of extraneous electrical signals
Oversensing
Power source that houses the battery and circuitry for regulating a pacemaker
Pulse generator
The rate at which the pacemaker's pulse generator initiates impulses when no intrinsic activity is detected; expressed in pulses per minute
Basic rate
The minimum amount of voltage (i,e., milliamperes) needed to obtain consistent capture
Threshold
Pacemaker response in which the output pulse is suppressed when an intrinsic even is sensed
Inhibition
A pacemaker malfunction that occurs when the pacemaker fails to deliver an electrical stimulus at its programmed
Failure to pace
