Q

PR segment

A

Appears as isoelectric created as impulse moves slowly. The av nod follows p wave and the time between end of atrial depolarization and the start of ventricular depolarization

Q

Ecg thermal paper

A

Has special heat sensitive coding and tracing is burnt on paper

21
Q

Super rapid heart beat like 150

A

Increase the chart speed

22
Q

If tracing shows tall wave forms

A

Decrease gain or sensitivity

23
Q

What is the default chart speed

24
Q

Default gain or sensitivity

25
V1 is placed
On fourth intercostal space at right sternal edge
26
V4 is placed
On 5th intercostal space on mid-clavicular line
27
Dextrocardia
Electrodes are place on right side of chest on same intercostal spacing and landmark. switch right and left lead wires
28
Peak flow pulmonary function test
Measures exhale air and can be done at home to manage chronic respiratory conditions
29
Lung defusion capacity
Pulmonary function test determines how effectively gas travels from lungs to blood stream
30
FVC
Maximum volume of air that can be forcibly and rapidly as possible exhaled after taking in a full inhalation
31
RV
Volume of air remaining in lungs after maximum exhalation
32
Meter dose inhaler
Use a spacer if possible put mouthpiece in mouth, close your lips around it, than hold breath for 10 seconds than breath out
33
Wondering baseline
Is an artifact upward and downward movement of the waveform and the isoelectric lines shifts locations
34
Isomatic tremor
Artifact appears as jagged peaks with irregular height and spacing
35
AC interference
Artifact appears as a series of small spikes creating a thick looking tracing
36
Wondering baseline occurs when
Electrodes are old or poor skin preparation occurred
37
Interrupted baseline
Tracing looks normal at the beginning than goes all over when electrical connection is interrupted
38
Somatic tremor
Is likely to occur if the patient talks during ecg
39
AC interference can occur
when lead wires are wrapped to closely together
40
Premature atrial contraction
Arrhythmia happens when atria contract sooner than should
41
Ventricular defibrillation
This arrhythmia occur when ventricles quiver uncontrollably
42
Prior to exercise stress test the MA should have patient
Sign consent form
43
Cardiac event recorder
Allows patient to record ecg when symptoms occur and can be worn for 30 days
44
Holter monitor
Monitors heart during normal activity for 24 to 48 hours
45
Maintance of electrocardiograph
Want to refer operators to manual for cleaning instructions for casing and stylus. Store lead wires and patient cable in a lose coil and don’t dispose of lead wires
46
Spacer use
Connect to inhaler to the hold the mist until the user can breath in
47
Spirometry test
Should be repeated 3 times
48
Patients should be sitting
During neubulizer treatment
49
10 electrodes are
Placed on patient when performing 12 lead
