Perfectly

rate may vary between 40-100 bpm
rhythm irregular
p waves upright in II, negative in aVR

sinus arrhythmia

How well did you know this?

Not at all

Perfectly

rate may vary between 40-100 bpm
rhythm irregular
p waves upright in II, negative in aVR
rate slows down

sinus dysrhythmia

How well did you know this?

Not at all

Perfectly

sinus node quite pacing

the next fastest automaticity focus “escapes to become the pacemaker

sinus pause/arrest

How well did you know this?

Not at all

Perfectly

sinus node momentarily doesn’t pace
one beat is missed
sinus resumes pacing or the next fasteset automaticity focus “escapes” to become the pacemaker

sinus block

How well did you know this?

Not at all

Perfectly

rate variable but normal at 60 to 100 bpm
rhythm irregular
p wave morphology variable (at least 3 different forms)

wandering atrial pacemaker

How well did you know this?

Not at all

Perfectly

rate = 60-80 bpm
rhythm regular
p waves upright or biphasic, different from sinus p waves
PR interval usually normal
late beat

atrial escape

How well did you know this?

Not at all

Perfectly

fast: 150 to 250 bpm
rhythm regular
has p waves and normal QRS
pacer cells in the atria very irritable

atrial tachycardia

How well did you know this?

Not at all

Perfectly

sudden onset

paroxysmal

How well did you know this?

Not at all

Perfectly

very fast: 150-250 bpm
rhythm regular
p waves inverted (before or after) or absent (buried within QRS)

paroxysmal junctional tachycardia (pjt)

How well did you know this?

Not at all

Perfectly

fast: 150-250
rhythm regular
p waves questionable, may be hidden within the previous t wave - can't always distinguish between PAT or PJT
QRS normal
umbrella term

supraventricular tachycardia (SVT)

How well did you know this?

Not at all

Perfectly

atrial rate of 250-350 bpm

rhythm: often regular with varying p:QRS ratios (2:1, 3:1, 4:1); sawtooth pattern
intervals: p waves in sawtooth pattern, pr interval=NA, QRS normal

atrial flutter

How well did you know this?

Not at all

Perfectly

rate: atrial rate >350; ventricular rate variable

vent rate: rapid>120, controlled70-10-; slow

atrial fibrillation

How well did you know this?

Not at all

Perfectly

rate: variable; fast 100-250 bpm
rhythm irregularly irregular
intervals: p waves of variable form (should see 3 diff. forms); not all p waves always conduct through to the ventricles
PR interval variable
QRS normal

multifocal atrial tachycardia (MAT)

one PVC:

isolated

every other PVC

bigeminal

every third PVC

trigeminal

every fourth PVC

quadrigeminal

3 or more PVCS

rate: fast…100-250
rhythm: regular or irregular
intervals: no p waves, QRS wide

ventricular tachycardia (v-tach)

form of rapid v-tach, twisting of points

torsades de pointes

chaotic; no discernible waves or complexes

course or fine undulations

ventricular fibrillation (V-fib)

straight line

no electrical activity

asystole

rate = 40-60 bpm rhythm regular p waves inverted when visible, may be in front of, within or after the QRS complex PR interval < .12 (consistant)

AV nodal or junctional escape

``` rate = slow,; 15-40 bpm rhythm = regular, but no p wave per R p waves = absent or not related to QRS pr = NA QRS = wide ```

idioventricular or ventricular escapse

has p waves and normal QRS | premature beat ectopic impulses

PAC ( pre atrial contraction)

p waves inverted, absent or following QRS and normal QRS | premature beats, ectopic impulses

PJC ( pre junctional contractions)

have p waves and wide QRS P waves occur while the ventricles are partially refractory( still repolarizing; might be seen on the preceding T wave) premature beats, ectopic impulses

aberrant beats

measured p waves: height and duration

< .12 sec in duration

PR interval: duration

.12 - .20

QRS complex: duration | R wave: height

< .12 | <= 15 mm

ST segment: soelctice horizontal deviation

-.5 mm to +1 mm

T Wave: voltage (height)

<= 5 mm

QT interval: normal duration

<.44 | should not exceed more than half of the R-R interval

``` Escape rhythms: rate = slow; 15-40 bpm rhythm = regular but no p wave per R P waves = absent or not related to QRS PR = NA QRS = wide ```

ventricular escape or idioventricular rhythm

``` Escape rhythms: rate = 40-60 bpm rhythm regular p waves inverted when visible - may be in front of, within or after the QRS complex PR interval <.12 (consistent) ```

junctional escape or AV nodal rhythm

``` Escape rhythms: rate = 60- 80 BPM rhythm regular p waves upright or biphsic; different from sinus p waves PR interval usually normal ```

atrial escape

``` Junctional rhythm: rate = 60-100 bpm rhythm regular p waves inverted when visible - may be in front of, within or after the QRS complex PR interval <.12 (consistent) ```

accelerated junctional rhythm
