Atrial dysrhythmias Flashcards
1
Q
Premature junctional contraction
A
- Retrograde P wave before, during or after QRS
2
Q
Atrial escape beat
A
- Pause followed by change in P wave - Atrial automaticity foci - 1 beat then SA resumes pacing
3
Q
Junctional escape beat
A
- Pause followed by inverted P wave before or after QRS
4
Q
Wandering atrial pacemaker
A
- P wave shape varies - Cycle length variation - Rate within normal range - Wanders from SA to atrial automaticity foci
5
Q
Supraventricular tachycardia
A
- P waves run into preceding T waves - QRS < 0.14 sec
6
Q
Wolff-parkinson white syndrome
A
- Delta waves from P - R - PR < 0.12 sec
7
Q
Atrial flutter
A
- Sawtooth waves - Atrial automaticity focus rate 250-350
8
Q
Atrial fibrillation
A
- Irregular rhythm - Continuous chaotic atrial spikes- erratic p waves - Rate 350 - 450 - Occasional random ventricle depolarization
9
Q
Junctional rhythm
A
- 3 + junctional escapes - 40 - 60 BPM
10
Q
Accelerated junctional rhythm
A
- Characteristic P waves - 60-100 BPM
