Question 0

EKG wave produced by an artificial pacemaker

Answer 0

Pacemaker spike

Question 1

A device that substitutes for the normal pacemaker cells of the hearts electrical conduction system

Answer 1

Artificial pacemaker

Question 2

Controls the rate and strength of each electrical impulse

Answer 2

Generator

Question 3

Relay the electrical impulse from the generator to the myocardium

Answer 3

Lead wires

Question 4

Used to sustain a patients heart rate in emergent situations

Answer 4

Temporary pacemakers

Question 5

Implanted inside the patients upper left chest and are left in place

Answer 5

Permanent pacemakers

Question 6

Commonly called external cardiac pacing, consists of two large electrode pads, which are most commonly placed in an anterior-posterior position on the patients chest to conduct electrical impulses through the skin to the heart

Answer 6

Transcutaneous pacing (TCP)

Question 7

Noted the presence of a spike and wide QRS complexes, the presence of an adequate carotid pulse and blood pressure, and an increased level of consciousness

Answer 7

Capture

Question 8

(Through a vein) a lead wire is inserted through the skin and threaded into a large vein leading into the right side of the heart and controlled by an external power source

Answer 8

Transvenous pacing

Question 9

Programmed to deliver electrical impulses at a constant selected rate

Answer 9

Fixed-rate, or asynchronous, pacemaker

Question 10

Generates electrical impulses when the patients heart rate falls below a predetermined rate

Answer 10

Demand, or synchronous, pacemaker

Question 11

Is simply the capability of a pacemaker to recognize inherent electrical conduction system activity

Answer 11

Sensing
