EKG flashcards
1
Q
- choppy interference throughout tracing
- related to muscle movement (shivering, parkinson’s disease)
A
somatic tremor
2
Q
- static looking tracing
- related to poor grounding or external electricity interfering with tracing (lights, computers, crossed lead wires)
A
AC interference
3
Q
- results from poor electrode connection
- caused by lotions, oils, or powders on the skin
A
wandering baseline
4
Q
normal EKG tracing of a heart rate less than 60 bpm
A
sinus bradycardia
5
Q
reflects a heart rate of greater than 100 bpm
A
sinus tachycardia
6
Q
- a break in the normal EKG tracing
- the sinoatrial node failed to fire
- not significant unless arrest lasts longer than 6 seconds
A
sinus arrest
7
Q
the atria are contracting at a rate much faster than the ventricles are contracting
A
atrial flutter
8
Q
- there is no organized contraction of the atria
- in a quivering state
- blood clot formation can occur due to stagnation of blood in the ventricles
A
atrial fibrillation
9
Q
- ventricles are in a quivering state
- no discernable waves noted throughout the tracing
A
ventricular fibrillation
10
Q
the heart stops
A
asystole
11
Q
- a junctional dysrhythmia is likely present
- typical impulse pathway from the SA node to the atrioventricular node is not occuring
A
P wave negative deflection
12
Q
- QRS wave appears wide and bizarre
- ventricular arrhythmia is occuring
- can be insignificant, but provider should be notified
A
premature ventricular contraction
13
Q
P wave
A
atrial depolarization or contraction
14
Q
QRS wave
A
ventricular depolarization (atrial repolarization is not visible but occurs during this phase
15
Q
T wave
A
ventricular repolarization
