Name the 5 Atrial Arrhythmias?
|
1. Wandering Pacemaker
2. Premature Atrial contraction 3. Atrial tachycardia 4. Atrial Flutter 5. Atrial Fib. |
|
|
Regularity:R-R Intervals vary slightly as pacemaker changes. Rhythm slightly irregular.
P Wave: Fluctuating P wave-changes as the pacemaker changes.Can be notched,saw-toothed & flattened.One P in front of every QRS & some may be difficult to see. PRI: may vary slightly, but normal measure should be less than .20 sec. QRS will measure less than .12 sec. |
Wandering Pacemaker
|
|
|
1. Has a P wave that is flattened,notched,sawtoothed,etc.
2. Caused by an ectopic beat. Will interupt the regularity of the underlying rhythm. 3. It is a single-beat, not a rhythm. 4. PRI-should measure .12-.20,but can be prolonged because of ectopic beat. 5. QRS will be normal-less than .12 sec. |
Premature Atrial Contraction
(PAC) |
|
|
Regularity: rhythm is reg. & R-R intervals are constant.
Rate: AR & VR are equeal; 150 - 250 BPM P Wave: one in front of every QRS. P may differ because they might be flattened or notched. PRI: .12-.20 sec. & constant, but may be hard to measure if covered by T wave. QRS: Normal <.12 sec |
Atrial Tachycardia
|
|
|
Regularity: R-R intervals are constant; rhythm is regular.
Rate: AR & VR are equal; 150 -250 BPM P wave: one P in front of every QRS; P may be notched, flattened,because of rapid rate & P wave can be hidden in the T wave. PRI: .12-.20, might be irregular & hard to measure. QRS: less than .12 sec. |
Atrial tachycardia
|
|
|
Fast beats cause heart to flutter.
Regularity: Atrial rhythm is reg. Ventricle rate may be irregular. Rate: 250-350 BMP P waves: 2:1, 3:1, 4:1, more P's than QRS, because ventricles are not able to contract,usually sawtoothed. PRI: Irregular R-R & not measurable. QRS: less than .12 sec-hard to measure at times. |
Atrial Flutter
|
|
|
Regularity: Atrial rhythm is unmeasurable; atrial activity is chaotic. V rhythm is irregular & no pattern.
Rate: 350 + BPM P: atria not depolarizing, instead they are fibrillating,thus no P wave. PRI: Since no P waves, no PRI to measure. 3.QRS: <.12-Supraventricular 4.Totally/grossly irregular |
Atrial Fib
|
